I posted a topic on them in the name them and shame category under suppliers. It has a lot of feedback on them. I've used them a lot in the past and have had several bad experiences.
They're very slow on shipments. If you're using them as a dropshipper be careful, I got a lot of negative feedback because of their slow shipping.
I've also had them send incomplete orders.
I had a couple bad orders shipped to my customers and it took them over a month to credit me back.
I wouldn't use them unless you have too. Their service is terrible. A lot of people have had problems with them. Checkout that topic I posted and good luck.
