Not to sound like a snob, but I wouldn't let these strings in the same room as my basses. Strings are the one thing that so many people take shortcuts on while it should be the last (IMO). It's a good price for an emergency set or for a downright beater bass to wear and an absolutely great price for those on a budget (right, kids?), but not for me. Wish they were around when I first started playing. I just hope any players that do a bit of prolonged playing don't consider these a bargain because I'd bet all of my basses that these strings change into a bronze-like colour wherever your fingers are in contact, have a high likelyhood of breaking while tuning and sound like absolute crap in two weeks.
Strings are such an important factor when considering the proper functionality of an instrument and if there is ANY advice I can give to new or younger players, it's that you get what you pay for...don't feel bad about using strings that are a third of the price of your bass (just remember: every manufacturer says THEIR strings are the best).
