Just curious on ppl opinions on the aurobindo kpins.

So I hear ppl complain alot about the aurobindo kpins. Are they really as bad as ppl say. My guy has some 1mg ones for $5 but if there weak and shitty like I see alot of ppl say I'm prolly gonna pass. Just curious on everybody opinions on them. There green with a 1 and just a slit on the back.
