Hello, the mouse is really well designed it looks like logiitech was tailor-made for my hand! And it works on the glass that's great. Broke down after one year, the charge lasts one day and the dial knob is broken. Fortunately, Amazon propse me a refund or replacement within three working days. Thank you The batteire want only supported two days at one hour of use per day. Logitech Announces 30-day autonomy !!!!
