I have the Patuoxun which is on for £7.99 I think and it is amazing. This looks like a rebranded version of the same thing for £6.99 as a lightning deal. It really is a good mouse and the battery lasts for months!
Not sure this is the same internals. This one is Bluetooth, I'm not sure if it comes with a Bluetooth USB dongle. So you probably need a Bluetooth enabled device. The other one comes with an rf USB dongle. Not saying this is a bad thing just something to consider.
