I think this is definitely a case of "you get what you pay for".
I gave this place a shot twice for brow threading based on all the recommendations it gets on other groups. The first time it was okay, brows were even but they weren't entirely thorough with removing stray hairs. The most recent time the girl took a giant chunk of hair of one of my eyebrows, rendering the pair horribly mismatched. :(
They don't give you a hand mirror to see up close so when I left I thought they looked a bit uneven but when I looked more closely at home I was horrified. Praying the mangled one grows back in quickly. :(
