I have 2 binders from this brand for couple months now and I would say this is an alternative to gc2b but won’t be exactly the same. I tried all of their half binders and their sizing are different (too small, too close to the armpits, kinda hard to put it on, the elastic band gets twisted). Overall, it’s good alternative since it’s only $20, fast shipping and free return.
