I have a Sony A 230 added myself as a 2nd body and was looking for a convenient remote control with which you can remotely trigger.
The Orginalbedinungen have been me frankly too expensive so I opted for this product.
A good workmanship, a proper range (up to 8m each trip, from 10 meters, it is a gamble ;-))
And you do exactly that what you will. Best Buy!
