This is a great product. I like the simplicity of the remote and how to set the strength of each function. Another addition I like is that the strength can be set to zero and I like this because I mainly use the beeper and the vibration. The battery life feels like forever and connects seamlessly when turned on, off, on, and so forth. The lock feature is handy when it is in your pocket. Since the buttons are front facing it might get pressed in your bag or pocket.
