It's a SCAM. They stole my money and never delivered the wristbands. I tried contacting them by phone and email but never got any answer. Luckily my credit card should reimburse me, but be warned!
Also, they lie on their forms:
on the proof form they sent me they report the BBB logo (Better Business Bureau) saying that they are accredited by the BBB, but this is actually not true (as clearly stated on the BBB website: http://www.bbb.org/houston/business-reviews/novelties-retail/wristbands-net-llc-in-houston-tx-90012599/customer-reviews )
In short, it's a SCAM.
