Microsoft MAIN-35956 Sculpt Ergonomic Mouse (L6V-00001)

This mouse really deserves five stars, but I am struggling with giving it that rating.This mouse is super comfortable, with the vertical orientation leaving your hand in a natural position as you use it. I've never had wrist or hand problems, but still I notice the positive difference in fatigue when I use this mouse. The mouse is very accurate, and the large glide surface makes it feel like it's floating across the desk. The buttons give great tactile feedback, and the wheel scrolls easily with the steps easy to stop on and easy to scroll from. This could be the most perfect mouse I've ever used, and is such a pleasure to use I bought one for home, too.So why the five-star struggle? This mouse is tall. Very tall compared to the mice I've used over the past 30 years. So tall, in fact, that occasionally (at least it's no longer frequently like when I first received it) when I reach for the mouse, I knock it off my desk. After so many years computing, and reaching for the mouse becoming a mindless activity, I'm so used to a mouse being a certain height, I simply don't reach high enough. So, the side of my hand bangs into the mouse, sending it flying (since the non-friction surface works so well). More often than not when this happens, the bottom cover pops off and the batteries come out. Of course, they never fall next to the mouse - no, I'm crawling on my hands and knees looking under chairs and desks.When I do this at the office it's a minor annoyance, since I have carpeted floors there. At home I have hardwood, and the mouse takes a beating when it falls. So much so that the wheel no longer works. I'm going to have to replace it, but this mouse is so great that I'm going to buy another one. But if I break it again, I may need to look elsewhere, just for my wallet's sake.

Works great with an 27-inch iMac. I have been using this in the office with the Windows 7 and the MS ergonomic split keyboard. The keyboard is definitely an acquired taste and a learning curve. But the mouse is great on day 2 and thereafter. Love the feel and the accuracy. It's not dainty. Good for medium and large hands. So I bought another Sculpt ergonomic mouse for the iMac at home. Replaced a big (sadly) failing Logitech mouse that we both loved. The MS Sculpt mouse works well. When the (rechargeable) batteries get low, the mouse behaves badly but does not stop working. Replacing with freshly charged batteries cures the issue entirely. We have replaced the battery once at home since it was new. The MS ergonomic keyboard and sculpt mouse seem to be super efficient battery-wise.At home I knock this mouse off the keyboard tray once in a while because it is a bit taller than the Logitech mouse. It hits carpet and seems to be none the worse.7/16/17 - Still happily using them both. The mouse works best if the dongle is less than 18 inches away. I have the dongle in a USB hub. The hub and its cables are ugly. When I hide the USB hub with the dongle attached too far behind iMac, the cursor gets jumpy. I always think it is a low battery, but it's not.

I've never used an ergonomic mouse before, so I don't really have anything to compare it to other than regular mice. I did try a roller ball years ago and hated it. But after 2 full days of use at work, where I literally mouse constantly for 8 hours each and every day and have a bad case of tendinitis to show for it, the wrist pain has greatly improved. It holds your hand at a much more natural and comfortable angle and is big enough where I cup my hand around it rather than pushing a regular one around with my fingers. This, in addition to a set up of 2 wrist rests - one I was told is too high so I put one that I thought was too short under my elbow to even it out - has led to a big improvement.I do have a couple small beefs though: it's a tad on heavy side, so if your wrist is feeling the pain, it's not necessarily effortless to push around. (But since it's helping to relieve the pain, it kind of cancels itself out.) And TWO AA batteries - hope I don't go broke just keeping it running. It's also a shiny surface which looks nice now but I'm sure will get mucked up with hand lotion quickly.But it is helping the pain immensely so I can't give it anything less than 5 stars. Will update if something goes horribly wrong!Update 3/7/14 - Still love it. The wrist pain is gone and I'm off vitamin B6 which I was using to manage it, and after years of toxic-level doses, that is a very good thing.Another update - I was reading an article about this mouse and it said it was designed so that a pair of batteries last a year. So there's some hope there too - my old wireless mouse went through batteries like crazy.
