Silent Partner e.Stringer
Silent Partner e.Stringer

Evaluations of the Silent Partner e.Stringer:

Kelly Ford, July 20, 2000:

   Place of purchase: Silent Partner (www.sptennis.com)

   Date of purchase: 3/2000

   Warranty: 5 years on everything except electric tensioner which is 1 year

   Price: $199

   Equipment:

electronic tensioner, two floating clamps, 2 point mounting, tabletop

   Experiences:

Extremely simple to use. Solid construction. Clamps are only fair, not great. One experience when a clamp opened after clamping.


Craig Kahn, Aug 29, 2000:

   Place of purchase: Silent Partner (www.sptennis.com)

   Date of purchase: 20/8/2000

   Warranty: 5 years

   Price: $199

   Equipment:

electronic tensioner, 2 floating clamps, 2 point mounting, tabletop

   Experiences:

Construction seems to be very solid - better than I expected from a $199 electric stringer. Clamps worked well and are adjustable with an included allen wrench. This is my first experience stringing tennis racquets and I found the instructions adequate and the machine easy to use. One major warning: get yourself a calibrator. After stringing my first racquet and noticing that the tension seemed too loose for the 63 pounds I had strung it at, I bought a calibrator and determined that my machine was off by 15 pounds. One good thing came out of that, though - I liked the power so much that I'm now stringing my racquets at 55 pounds!


Fred Daoud, May 24, 2001:

   Place of purchase: Silent Partner Canada (www.sptennis.com/canada.html)

   Date of purchase: 01/2001

   Warranty: 5 years

   Price: $169

   Equipment:

electronic tensioner, 2 floating clamps, 2 point mounting, tabletop

   Experiences:

Hey Joe! Great site, great job, keep it up!
This machine is indeed solid and easy to use. The instructions are clear and I was able to string my first racquet in an evening (from the arrival of the package to the completely strung racquet). Then you get the hang of it and it takes less time. I find the electronic tensioner to work very well. Just one warning: make sure to wrap the string snuggly into the tensioner before activating, or else the tensioner could get stuck. Happened to me twice until I figured out why (string was wrapped too loosely), and never happened again. All in all I am very happy with the purchase.
A note to Canadians: particularily good value given how expensive US dollars are these days, because it comes from Toronto, you can pay in Canadian dollars, no duty, and faster, cheaper shipping. Does not mean that it's not a good buy for Americans also!
One last note: I searched high and low for a stringing machine, asked around, and I think this is a great purchase for personal use.


Lin, Dec 14, 2001:

   Place of purchase: Online (www.sptennis.com)

   Date of purchase: 11/2001

   Warranty: 5 years/1 year

   Price: $199

   Equipment:

electronic tensioner, 2 floating clamps, 2 point mounting, tabletop

   Experiences:

I like this machine overall, price has a lot to do with that. The tensioner works well, although mine is about 5 lbs. under what the knob says. I string 5 over what I want and it ends up just fine. The floating clamps are not so great. I had to put thread lock to keep the bolts in, they were crimping 17g string out of the box. Also had to bend the fixed side "losening bolt had no effect on that side of clamp". So I had to tinker with it a little, hundreds less than the nearest model, worth it to me.


Humberto Florez, Dec 25, 2001:

   Place of purchase: www.sptennis.com

   Date of purchase: 10/2001

   Warranty: 5 years/1 year

   Price: $199

   Equipment:

electronic tensioner, 2 floating clamps, 2 point mounting, tabletop

   Experiences:

Nice machine for the price.
The stringer is easy to use. The instructions are very detailed and well illustrated. The information on the website is quite complete, with patterns for most racquets.
I had a problem with the engine gear box and the manufacturer replaced the entire engine under warranty. Aftersales customer service is excellent. I suggest the gearbox is reinforced for durability even if this means another $20 in the price. The main axel should be extended to cross the box's housing and give it more support.
Good machine overall!!


Chris, Feb 25, 2002:

   Place of purchase: Silent Partner

   Date of purchase: 02/2002

   Warranty: 5 years

   Price: $200

   Equipment:

electric motor tensioner, table-top, flying clamps, 6 point mouting system (extra $50) worth the money

   Experiences:

This is a fantastic little machine. I have strung 4 racquets so far with great ease. The tensioner takes a bit of getting used to. This is my first time using flying clamps. The ones supplied work very well. For the money this is far better than a drop-weight system. It took me about 30 minutes on average to string each racquet. On an Ektelon I can string a racquet in about 17-20 minutes. I haven't noticed any flaws in the unit. It is extremely well made. Although it is a little bit slower, the quality of the string job is every bit as good as a high-end machine.


David Stelly, May 23, 2002:

   Place of purchase: Silent Partner

   Date of purchase: 2002

   Warranty: 1 year

   Price: $250

   Equipment:

electronic motor tensioner, table-top, flying clamps, includes modification for 2-pt to 6-pt mounting

   Experiences:

Easy to set up and use. Good tensioning with 5-minute motor pre-warm-up (usually while prepping other items, e.g., string removal, string measurement). On-line video demo provided adequate introduction to procedures, and combined well with on-line internet stringing patterns. Packs easily into a trunk. No problems to date. Highly recommended.


Humberto Florez, June 23, 2002:

   Place of purchase: Silent Partner

   Date of purchase: 2001

   Warranty: 1 year

   Price: $199

   Equipment:

electronic tensioner, table-top, floating clamps, optional 6-point mounting

   Experiences:

I just finished stringing the third racquet with the new replacement tensioner I received from the manufacturer (Duce Industries).
The results were terrific. This is a much stronger motor equipped with a more robust gear. The shaft is quite ridgid and does not bend as in the previous model. Great improvement in speed and precision as well.


A. Fleischman, July 27, 2002:

   Place of purchase: Silent Partner

   Date of purchase: 07/2001

   Warranty: 5 years

   Price: $200

   Equipment:

Electronic Tensioner (30 lb to 80 lb)
Two-way motor for easy string release
Ultra convenient string gripper
360 degree racquet rotation
Brake
Micro adjustable mounting system
Two premium all-metal flying clamps
Awl and needle nose pliers included
Illustrated stringing instructions
Access to full set of stringing patterns
Download Owner's Manual
tabletop

   Experiences:

The machine takes about 10 seconds to pull the string which is long. It is extremely hard to pull thick textured strings. Set up takes at least 10 minutes and string times extended about 15 to 20 min. String gripper is of poor quality. Gripper broke after 6 months, but company easy to deal with and replaced gripper. When pulling at high tensions, frequently the racquet pops out of clamps. Though there are many negatives, the machine does get the job done and for $200 plus $40 shipping and $50 for 4 point mounting (recommended) the machine works fine to string your and your friends' racquets. I strung at least 150 rackets on it. I am now changing to a different model because I want to move up to an upright of better quality (though more expensive). Overall, the machine is probably the best in the price range compared with similar Klippermates (drop weight). It is probably more accurate than a drop weight.


M. King, November 07, 2002:

   Place of purchase: Silent Partner

   Date of purchase: 10/2002

   Warranty: "satisfaction"

   Price: $279

   Equipment:

electronic tensioner, 6 point mounting system, tabletop

   Experiences:

I received the stringer about 7 days after placing the order online. I bought the optional 6 point mounting system. I also purchased a calibrator from Gamma. Before stringing anything, I spent time checking the calibration. The machine says to warm up for 5 minutes, but I found the calibration accurate right from the start. The mounting system is very good. The string retention system works very well. The flying clamps are adequate, but not great. There are no instructions, but I watched the demo video at sptennis.com, and I had no problems at all. I have strung many racquets on my TR Stringer (junk), so this was a breeze.
The only negative comment is that the mounting system is just a hair too low to allow the handle of the racket to pass over the tensioner. I think I will put a couple of flat washers in there to raise it up before I string another racquet.
Overall, I think this an excellent home stringer. It is much faster and easier to use than other machines of the same price range.


Chris, August 13, 2003:

   Place of purchase: Silent Partner

   Date of purchase: 08/2003

   Warranty: 5 years

   Price: $279

   Equipment:

tabletop, electronic tensioner, 2 flying clamps, 6 point mounting system (optional), tools and manual

   Experiences:

Delivery to Arizona took 7 days. Extremely simple to put together. I strung some rackets on a drop-weight machine a few years ago and so far I am impressed. The first racket took me 1 hour, the third only 35 minutes. I think the clamps work good and the tensioner-system is very user friendly. I used a gamma calibrator and the machine is extremely precise. Racket turns >360 degrees as advertised and the whole unit is very stable and solid while working with it.
If you are looking for a simple machine that is easy to carry around and easy to use I would highly recommend this one. The only small thing I hope they will improve is the manual provided. Kind of hard for someone who never strung before. But this website helps those problems to the past.


tennis fan, October 17, 2003:

   Place of purchase: Silent Partner

   Date of purchase: 09/2003

   Warranty: 5 years on everything except electric tensioner which is 1 year

   Price: $279.99 + $20 shipping

   Equipment:

tabletop, electronic tensioner, 2 flying clamps, 2 point mounting (additional 4 points inside)

   Experiences:

Very easy to assemble and start to use. But I bought this machine thinking electric tensioner should provide more accurate tension compared to drop weight. But I'm really disappointed after I strung my first racquet.
I set the tension to 65, but after completed, the strings (both cross and main) were still very loose. I borrowed a calibrator from my friend and did the following test:
tensionafter 3 scndsafter 5-8 scnds
55~52~47
60~55~60
65~60~55
As you can see, the tension dropped pretty quickly. Since I'm a beginner (stringing), the time I used to clamp the string is varying, this makes the entire racquet tension uneven. I'm not quite sure why it started to lose the tension after ~3 seconds (anyone knows?). Because of this, I returned the machine (within 30 days, they only charge shipping which is $20).


jd coach, April 5, 2005:

   Place of purchase: Silent Partner

   Date of purchase: 2004

   Warranty: N/A

   Price: $250

   Equipment:

tabletop, electric tensioner, 2 flying clamps, 2 point mounting

   Experiences:

I've been stringing for years so I never looked at the instructions. The clamps needed adjusting. I had one nut strip so I had to find a replacement. I bought the machine so that I would have a machine when I traveled with my son to sectional tournaments. The USTA Intermountain section covers 6 states so you always were on the road. The machine was easy to use and worked great. I changed machines though, when I was able to pick up an old Ektelon standup model. I went for speed rather than convenience.


David, Jul 29, 2008:

   Place of purchase: Silent Partner

   Date of purchase: 02/2007

   Warranty: N/A

   Price: $279

   Equipment:

tabletop, electronic tensioner, 2 flying metal clamps, inside 6 point mounting. It came with a reel of Silent Partner's synthetic gut. Came with needle nose pliers, hex keys, and awl.

   Experiences:

Delivery time was 5 days.
Very easy to assemble.
Did not use user manual for machine.
The quality of the manual is good.
The handling of the machine is very good.
The clamps have to use a hex key to adjust.
The mounting system is very good and does not block holes.
I face some problems with the tensioner, which after about a year started to move from 65lbs to 45lbs and will not be exact and consistent throughout the stringing.
I am choosing a crank machine next time, and definitely a different model. But it did do good for a about a year.
