Summary: i bought a Joybee GP1 Mini Projector. i had never heard of this brand but decided to try it. my mistake. the products instructions were extremely poor. the projector won't hold a sync with the source. i tried unsuccessfully on three computers. the web page was of little help. i tried customer support. after three attempts at emailing them, i decided to return the product. it took two hours of calls just to get a rma.
