Logitech Ultrathin Touch T630 Wireless Mouse - PC - Black

Pros: Sleek and portable

Cons: battery life

I use this bluetooth mouse with a Lenovo Yoga 2 Pro so the mouse is ultra portable to match. It's a small device but surprisingly easy to maneuver without feeling too small. The right/left buttons click a bit harder than I'd like but the tactile feedback makes it clear that you clicked the buttons. The touch control replacement for a scroll wheel works well, too.
The main downside is that the battery last only a matter of days. You either have to remember to turn it off or routinely plug it in. The micro-USB connector is on the bottom so you have to turn the mouse over to charge it up. It would have worked better to have it on the side so the option to use it as a corded mouse would be there in a pinch.
I love this mouse for its portability and feel but I'd like it better if the battery lasted at least a month. Most Logitech mouse products run for months on a single AA battery. Bluetooth headphones run for days in standby mode. It's not clear why this only lasts 2-3 days. « less

Pros: responsiveness, ease of use,compatibility,size, multi-pairing

Cons: size, battery life, price

I will start by saying that even the "not so great" stuff is easy to cope with but if someone were to have an issue I suspect that these are the main concerns you will hear about.

1) responsiveness-This is a highly responsive mouse. I deal with almost no lag unless it is a brief time switching between dual pairing. I have used it on almost every surface of which I can think, and the only one that it absolutely doesn't work on is glass. Of course, if you use it on loose cloth (like a blanket) it will behave erratically (the cloth moves). The contour of the terrain the mouse is moving on will affect what you see. I often use my leg though and it works fine.

2) ease of use- there is a 2-way switch on the bottom to move between 2 possible channels (dual pair) and one for on off. there is a simple button for connecting, not the usual connect button that requires you to hunt a pin or specific instrument. after that it is click with 2 fingers or one finger going right and left. you choose. there is simple scrolling by pulling strait up the center. (Windows 7 can use the flip ability by swiping from the edge to the center in the same manner that Windows 8 can go to the start screen).

3) Size -it is small. this makes it super portable! it also makes a little difficult to use at first. It says it is about the size of a credit card area wise, and it is. It is also about the height of a pen's diameter.

4) multi-pairing - you can pair it with 2 devices simultaneously and use the switch on the bottom to switch between the two.

5) battery life- depending on use and if I remember to cut it off. I am going to assume that like me you tend to not be concerned about your battery powered mouse. I got 1 days use, and the battery was dead. but it is rechargeable. If you remember to turn it off, and or recharge it regularly, then I don't see a problem.

6) Price- weighing at about $70 when I bought it it is a bit more than I imagined paying for a mouse. For 2 decent mice it is probabl ... « less

Pros: Size, rechargeable battery, and responsive touch surface.

Cons: It is a bit flat and shows wear early on.

I've owned both the white and black version. They are the same in terms of functionality and build quality. They both have a flaw in that the material used on the top portion of the mouse wears over time. On the white version, it wore to the point where it was discolored. It worked perfectly fine, but began to look horrible. The black version appears to be equally susceptible to wear; however, it is less noticeable given its color.

In terms of functionality, it is great. It pairs well with two separate devices. I use a Mac, so it is worth noting that you will need to install the Logitech driver software to get it to work well. It works without it, but it's just not as fluid for some reason. Maybe that's changed, but that's how it was for me. The size is great for portability, but it is on the small side. It's relatively flat and can be difficult to use for extended periods of time. Recharging it is simple and fast. Overall, it is a nice mouse, despite its shortcomings and it looks great. It's on the higher end of the price spectrum. so if money is an issue, there are others that work just as well. « less
