I bought 1 pack of these just to check out if HB can offer good quality with lesser price like they do with guitars and i was shockingly disappointed. First string broke when i tried to put on my guitar. After tuning i always stretch fresh strings a little so they stay in tune better. So 1st string broke before i even played on it. Strings completely lost their brightness after 2 days of playing which is not okay even for a 3$ strings i think. 6$ strings for example can stay bright for up to 10-14 days of playing guitar. And the last thing, 4th string broke 3 days after i installed it, right in the middle of my street performace. Of course that happens sometimes, but 6$ pack used to server me MUUUUUCH longer. Afer strings lost their brightness i also found out that my guitar sound different, less volume and also sound lost like A LOT of highs so i cant even break throught mix, which never happened to me with this guitar and with any other old strings (assuming i always use the same gear) In consclusion i'd like to say you are better off buying any 6$+ pack, they'll server you much more, or buy elixirs they can serve you a dozens times more.
