Now, I'm not a snob with regard to the bass guitars and I'm not a person willing to spend too much money for stuff either.
I got these from Thomann for free when I bought a cheap but solid HB jbass and one of the strings was defective, yes an entire set for one string (props to Thomann for that, their service is incredible). These strings were considerably better than the stock cheapo strings. For the price I find them very usable and reasonably long-lasting, although they'll obviously lose their brightness after some time (like any other strings...), I'm using this set for two months now and it is still playable.
There may be better strings out there but the price/performance ratio of these is unbeatable. Personally, I see no reason to buy some expensive Daddarios that last about as long as these, when you can get 4 sets of the HB strings for the same price.
I'm certainly going to be buying these exclusively from now on.
