I don't usually write reviews but so far I really like this keyboard and mouse set. I use this for work, 8+ hours constantly. I usually charge my keyboard after work, which takes about 6 hours, and before bed I charge my mouse. It works fine for about a week and I found I have to charge the mouse for 4 hours after that to work. It began to die out faster as the week went by. Now, after almost a month, the mouse doesn't even hold a charge. I hope to get a replacement mouse if not a refund. I can't work like this, I ordered this because it was wireless and I work on a dual monitor laptop. I'm afraid the keyboard will do the same in a month.
