Vertical External Battery Grip w/ Remote Control for Nikon D3100/D5100

Pros: It's affordable and the quality is quite competitive. It comes with a remote which is a plus factor. I like the idea of having included that small thing. Unlike other battery grip that there's no remote with it.

Cons: There's no particular cons aside from that you have to align the remote to the sensor otherwise it wont trigger.

Other: I have no regrets of buying this battery grip, I can recommend this to all NIkon D3100 users. You have to have this as part of your accessories.

Pros: Very good product, well made, cheap, reasonable quality material

Cons: There´s only the shutter button, i miss the dial for exposure. The remote works only if it´s pointed directly to the front.

Other: It´s a good product for beginners but impossible to be used by professionals. Why you don´t have one with the dial like the original one?

Pros: - Battery Door holder - Perfect Fit - Quality Battery Terminals - Half-press Shutter - Infared Remote Control comes in real handy when trying to include yourself in the picture. - Ability to take portrait pics without awkward camera holding -

Cons: - Could have added some rubber to make it feel less plastic-like

Other: This is a must for camera enthusiasts because your battery runs out quickly on lower-end DSLR's. Also I love taking portrait style pics now because I don't have to stretch my hand around.
