When I first turned it on, the remote control didn't work. I replaced the battery and, "lo and behold", the remote control came to "life" (the light came on). Connected to my phone very easily. Minus 1 point for a faulty battery, but the remote itself works well.

It works but you seem to have to reconnect to bluetooth every time you want to use it. Just have to keep that in mind.

Since this is a repeat purchase, I will give advice, if the remote control does not work, then replace the battery. Of the 3 remote controls purchased, I replaced the batteries in two.

Good shutter to eliminate shaking the phone.

Works as advertised, the only reason I couldn't give it 5 out of 5 is because the battery it came with was dead on arrival. From other reviews I've read it does not seem to be an anomoly.

useful to eliminate camera shake.
