Actually, two are different in at least one aspect. The first one (in the picture) uses a CR2025 Button Cell Battery which is disposable (as do the ones direct from Sainsonic). The Amazon ones say they are rechargeable (but they are not!!) and two to three times the price.
So, we must assume that they are all the same, except for the name/logo printed on the top on the bridge (the first has 'DLP' and the other two have 'Gonbes') and they are on opposite sides, and of course the prices.
Edit: After a small amount of research, they are manufactured by Gonbes Technology CO.,Ltd. Shenzhen, Guangdong, China and are model number G15-DLPEdited by OZReddog - 1/19/14 at 6:48pm
