I don't really know. There is not much info about them on the web..They claim to have been in business since 95, but their website was registered on 11-22-06 and expires on 11-22 07.
They state on the site on the gaurantee page that all of their items are either used, refurbished, etc..and do not come with any type of warranty.
They do claim that they will accept returns.
Also I notice that alot of their phones do not come with a SIM card..
If you are going to do business with them I would try talking to them both on the phone and email and see what kind and how fast of a reply you get..Probably would ask about a sample order too...Read their FAQ page, help page and about us page also, it kind of gives you a feel about the company and how they are operating..
