Best remote page turner!

When it comes to remote page turners, what should you look for before buying one?

I have recently gotten back into reading with my kindle and I wanted a remote control page turner. The one decided on works on the Kindle, phones, tablets and any other touch screen. The clip charge time of 3hrs per day and one charge can last 15 days, It is thin, mini and convenient with a connection reach of almost 100 ft.
