Difference PRO’S PRO Challenger I and II

[DucK]

Can someone write the difference between
PRO’S PRO Challenger I and
PRO’S PRO Challenger II
stringing machines?

Thanks in advance.

Hi,

as far as I can tell the Challenger I has a new mechanism that keeps the string gripper in place so you don't have to fix it with your hand.

The Challenger II is just an "ordinary" manual machine without this mechanism...

I test it few days ago.
It's good stringing machine. It's really unusual to string it with this new mechanism but after few strings, it's very easy to string racquet. :)
Stringing claps are really bad and I suggest replacing them.
