This is by no means a brilliant lead. For me, it does the job intended, reasonably well. For the price it is good. The jack ends are covered pretty well as theres a solid screwable cover on it. So, unlike a lot of other cheaper leads, it can easily be fixed if broken.
If you gig frequently, I wouldn't recommend this lead. You are much better off paying a bit more for a sturdier, more reliable lead, which will last longer in the long run. I would recommend buying a few of these for rehearsals and home practice. For the price, I find having a few about is good incase one happens to break. I haven't broke many, although, you should get a year or more out of them, depending on how you look after them and how much you use them.
Overall, a good purchase, that definitely does its job well.
