I've used this cable for rehearsals and some club gigs for the last 3-4 years.
Never had a problem with the jacks/connectors. The cable material itself is thick enough and easy to handle, it bents easily around amp corners, among pedals etc.
I cannot make a safe comment on the signal clarity, although I do not really have any complaint either, so I guess the signal is pretty clear!
Considering the price of the product, I say it's a reasonably good deal! The cable is rather not in the high/pro quality range, but a good quality product for sure. Cheers!
