Logitech 920-000383 MX 5500 Keyboard Mouse (Refurbished)

I like the keyboard much more than the mouse, even though the mouse is supposed to be some awesome technological marvel (at least that's what some people rave about). As another reviewer said, the keys on the keyboard feels soft when typing, which is great. The keyboard is also fairly light and sturdy. I have my computer set up in my bedroom and I use the keyboard while sitting in bed. I just grab it with one hand from the wrist-rest area and place it on the bed without much care. The text zoom shortcuts are nice and works well with Firefox. Battery life is also very good. I still have 111 days left, according to the software battery monitor, and I've been using this several months. About the mouse, there are a lot of buttons that can be programmed. Unfortunately, there's no double-click option in the software. I had that capability with my MS Intellimouse Explorer and used that for years, so it was disappointing that this state of the art mouse didn't have that. I assume it's a Logitech problem. The mouse has a good battery life. I think I have to recharge it about every 3-4 weeks (maybe even less frequently). The main problem I have with the mouse is the accuracy at slow speeds. If I override the acceleration curve by using the built-in Windows mouse control panel, it works alright, but for some reason, the supposedly more tweakable Logitech software can't get me a very good user experience. Unfortunately, the Windows mouse control panel conflicts with the Logitech software (switches dominance when I use different programs or restart) I can overcome the poor slow speed accuracy by setting a very low acceleration curve, but when I use the mouse more normally (like clicking links on a website), it doesn't move fast enough. So, I compromise and use the Logitech settings only and use the acceleration curve that allows me to aim accurately 90% of the time. Maybe it's a personal thing, but I didn't have these problems with my old MS mouse.
