It's pretty awesome for such a price! It definitely gives you great posture, I was sitting up straight like no other! although i wish they could improve on the rubber smell otherwise it's wonderful!

^^^^^ was my review when i had it for 15-20 days, now-- after ordering it on Jan, 21, 2012-- it's SO useless. I've washed it with care, it smells like rubber, and it's pretty nasty. I'd rather pay $$$ and buy something that works the way it should.
