The remote control does work without batteries and is compatible with the Nikon D7000. The case is very light, the whole looks solid. There is a little play in the housing means something move but it has no impact on the operation. The release button is not as sensitive as that of the device, but we found it fast enough, this is a hold function which allows the poses in Bulb mode.
The product was delivered on time, packaging is correct. A small price and a good product!
