Other modern programmable mouse software do not require this kind of workflow and save their changes instantly, so I dont know why this mouse is stuck with early 2000s firmware technology. And I cant beat the price. I just received a pair of these sandals and they fit perfectly. I will definitely be getting him another pair. Its waterproof so maybe next time Ill have it in the shower with me instead of on the counter. I wish it was just a bit longer. The new cusioned sole is so comfortable and was able to walk around paris for the whole day with no discomfort The longest part was tightening everything down. I purchased two of these and the batteries were dead within a month. The Bluetooth is a nice bonus, he wears them when hes out with the dog too.
