Trust Siano Wireless Bluetooth Mouse - 1600 DPI, Ergonomic Design for Laptop, Tablet & PC - Smooth Scroll Wheel for Office Work, Gaming & Home Use - Black

Swift delivery and good mouseArrived promptly,easy to set up with my new Windows tablet & now automatically links to tablet when I switch both on.Have not had much luck with Bluetooth devices before,but this one is great.True ,Bluetooth can use up quite a lot of power,not particularly noticeable though on my device,but in any case,being able to use a mouse without having to use up a.USB port is great.delivery and item ok, however i know this isnt seller fault but no usb inside package or mouse to connect to pcKept disconnecting, even while in use, and would not reconnect very fast. It was lagging terribly as well. Wheel kept jamming in the same place each time. Enfuriating! Don't waste your money.It's batteries have lasted just 3 weeks before it's stopped working completely; it was struggling for the last week. This is my first non-wired mouse so I am not sure what to expect but I cannot justify replacing batteries around 20 times a year surely??
