I was looking for a no-frills, full-size, Bluetooth mouse to use with a Surface Pro. I found the Sculpt Comfort on sale and, after a little research, picked one up. I've been very satisfied with this mouse so far, and it matches my use case perfectly.
I spend a lot of time on my computers so this mouse gets heavy use. I do development work on the Surface Pro so I'm more concerned with connection stability and accuracy when selecting text and navigating menus than I am with millisecond response times. Comfort and button convenience is also a big deal since I'll spend time online troubleshooting or researching and I want to be able to manage my browser with my mouse. I use the "claw" grip where my index finger is on the left mouse button, my middle finger is on the mouse wheel, and my ring finger is on the right mouse button.
The Sculpt Comfort mouse fits my hand well. I don't feel like I have to overextend to reach any of the buttons but nothing feels particularly cramped. Your mileage will vary, but it seems to be a good size for an average sized male hand. There isn't a palm rest or thumb support, so if you typically rest the back of your hand on the mouse then you might find that a little inconvenient.
The buttons have a good tactile click when pressed and the mouse wheel scrolls nicely. The mouse wheel is "4-way" in that you can push it left and right as well as scroll up and down. In previous Microsoft mice that use this type of mouse wheel the left and right buttons were either too soft, so you hit them accidentally, or so stiff that they were inconvenient to use. Sometime in the past few years they managed to get it right, though, so the mouse wheel left and right buttons are actually useful here. This mouse has a "swipe" Windows button that sits where your thumb will naturally rest. This button that can be pressed or it can be swiped up and down. This swiping motion does take a minute to get accustomed to, but once you adjust it's every bit as easy as pressing a button. There's also slight haptic feedback after you swipe, which is helpful.
It's accurate enough for development work and most general computing needs. I wouldn't recommend this mouse for artists, designers, or gamers, but for my use case it's great. There's never been a situation where the mouse's accuracy has gotten in the way of any work that I've done, which is all I can ask for.
The Bluetooth connection works well, pairs easily to Windows 10, and hasn't given me any problems. Again, it's never gotten in the way of any of the work that I've been doing.
Build Quality and Materials:
The Sculpt mouse feels solid and the removable battery compartment clicks into place firmly. Be aware that the shiny plastic is a smudge magnet.
My computer is a tool to get work done so any interface is being judged on whether it will help me or hinder me. The Sculpt Comfort mouse is a good, consistent tool that has never gotten in the way of getting work done. I've yet to come across any phantom double clicks, jittery pointer motion, uneven or stuck scrolling, connection issues, or problems with lag or accuracy. If you need a full-sized Bluetooth mouse that's well built and won't get in your way, the Sculpt Comfort will do the job.
