Logitech Ultrathin Touch Mouse T631 for Mac

This mouse is insanely small and thin! Great as a travel mouse or for kids. I have 2XL hands and have no problem using it, but my initial impression was negative. I bought it because I left my usual Magic Mouse behind and I'm traveling, so Amazon "next day" to the rescue. When it arrived, I immediately thought "oh dear ... well, better than nothing and it's a great size for a travel mouse or give it to one of the kids." After less than the first day of use, I realized I'd forgotten all about it -- it's as easy to use as the Apple mouse.One thing to note, at least for OS X, the scrolling is poor until you install the driver and reboot, then it's liquid smooth. The driver download link is included in the box (samsung.com/download/t631) and it's about a 50MB file that installs with no drama.Note that it has some cool features such as supporting two bluetooth host devices (a mechanical slide switch underneath toggles between "1" and "2" ... this was a major selling feature for me because I have two laptops ... my sort of "dual monitor" solution for traveling.) I still prefer using a virtual desktop app, but it overcomes the problem I had of the two Macs each trying to grab the mouse connection and a lot of boring software clicks to get from one to the other for specific tasks. It's about a 3 second handover process to flick the switch between 1 and 2, then bluetooth does the rest with no intervention.It also works as a mouse on the Nexus 10 with no fiddling, just click search for device, then pair ... bingo. Quite handy once you have the Nexus with a bluetooth keyboard if you want to do precise work.It charges off a micro USB cable, supplied in the box, but that's (for me, at least) one less cable to carry. Battery isn't an issue, it has an off switch, but left on, it seems to last about two days. I charged it this morning. It's little blue pin prick light glows and pulses slowly, then it turns solid and the preferences app updates as you unplug it to report a full battery of charge (no percentage, no estimated hours of remaining battery.) Good enough, but the metric Logitech offers (one minute of charge equals one hour of operation) just suggests that if you have the cable and it dies, you're only five minutes away from ample battery. Because the connect is underneath, it disables the mouse entirely during charging, but since you're talking about just a minute or three to revive it, I guess that concession to design aesthetics is fine by me.I saw some comments on it being difficult to click on soft surfaces (like a mattress) which I don't quite follow since it does the original "jeans test" from Apple ... you can use your knee as a mousing surface ... it seems to track beautifully on any surface except a glass table.This device raises my opinion of Logitech up to equal Samsung and even Apple itself.

I purchased this mouse to use as a travel mouse with my Venue 8 Pro and Microsoft Surface Pro 2. It is small and light enough to always have with you. I place it in a pocket in my backpack when headed to my college classes, and if I end up doing some studying on campus, it is super handy to have a mouse handy and always ready. I find that I actually use the gestures included with the mouse, unlike previous products that promised decent gestures but were plagued by bugs. The scrolling is super smooth, and I like being able to swipe in from the sides to switch tasks or bring up the options menu. I also tested this mouse with an Android phone, the Samsung Galaxy Note 2, and it worked perfectly. The ability to switch between two devices is awesome and I use this often. Although it would be nice to have more than 2 assignable bluetooth devices, bluetooth is extremely easy to pair on this device. You just push the sync button, and your host device will then see the mouse and be able to connect with it. Takes about 10 seconds once you get used to the process.I have not had difficulty with the clicking action of the mouse like other reviewers; it feels very natural to me and works extremely well. I knew that I was getting a small mouse (which is WHY I bought it), so I knew I'd have to use a fingertip grip. This isn't as bad as others make it out to me, and it feels extremely accurate and precise. Others have said it is hard to click on a sofa or soft surface, but I find it is still relatively easy to use in those situations. I never experienced issues while mousing on my leg. I also keep a small foam mousepad in my bag, and if I put that down on a couch I have *zero* problems. I also found the middle click to be natural. Once you use this mouse for a day the middle click location (about 1/2 back from the front of the mouse) is perfectly natural.The only downside I have found to this clicking action is that you cannot keep one mousebutton held down and click with the other. A good example of when you would want to do this is if you play FPS games, you cannot right click and hold to zoom in with a scope, then click with the left button to shoot. You can *only* right click or left click with this mouse, not both at the same time. Once again, I bought this for school so I didn't expect it to be a gaming mouse. That being said, it is fine for games like Minecraft or any others that don't require 2 mousebuttons to be held down at once.Overall I am extremely impressed with this mouse given its size. I would recommend it to anyone as a travel mouse.
