As one of the below reviews says, they're cheap, that's the only good part of the service. I actually spoke to them on the phone most of the time and they were quite good up until the order of swing tags came, and was missing letters. I asked them to reprint and said ill do business again and put this bad first impression behind them if they provide me the next 500pcs half price (Not much to ask for $30 off to continue a business relationship). 2 representatives got the email, neither replied, after calling them and trying to explain that they were the fault behind my prolonged launch date, they said well reprint and don't care about long term business, and hung up.
If you're up for a cheap gamble ; a product that is sometimes right sometimes wrong, go with these guys. If you want someone you can deal with and depend on long term, look elsewhere.
