Summary: This was my first wireless mouse as i was hesitant to get one because i hate wireless things as the reliability is good usually. However this thins surprised me as it plugged right in and worked with no issues the whole time i had it. Then one day it just stopped working, Until then it was great. it was very comfortable and has back and forward buttons which i love and will not get a mouse without. It used two aaa batteries. It looked good but probably could look better.
Summary: Mouse wheel? Check. Good number of buttons? Check. Comfortable in hand. Check. This would be a great mouse, and is a great mouse - when it actually stays connected to the computer. It works on about a 4 to 5 min basis then I have to unplug it and replug it back in. Also it doesn't turn off automatically or when i pull the USB stick out so it just stays on and the batteries die really quickly. Mouse looks good from the picture, horrible in practice.
Summary: I ordered this 9/12 and 11/8 it just stopped picking up the signal and didn't work. In the middle of a busy work day too. Now, I have to go buy another one, drive to the post office to send this back and pay to ship it back because my "window of time to return" expired on 10/15? Save yourself the trouble, don't buy. I mailed this mouse back on 11/8/12 (at my own expense) and requested a credit from Amazon. It's now 2/2/13.
Summary: You can't program the buttons, so when I push the "back" button, my screens all shrink. The "forward" button does the same thing as the wheel button. I can't believe it. How do these companies stay in business!!!! aaaaarrrrrggggggg. Sending it back.
Summary: This mouse was the size that I wanted. It was easy to install and easy to use. The major problem is durability. I used for one 10 hour day. The next day the scroll wheel quit operating after 30 minutes. For my work a mouse with out a scoll wheel is useless. I have been using a Microsoft 6000 mouse for 5 years. It still works like it did when new. I wanted a larger mouse for more hand comfort since I use my mouse coninously in my work.
Summary: I purchased the K72370 specifically because I was happy with the K64390 wireless mouse that came with my kensington wireless keyboard desk set. The only problem I had with the deskset was that sometimes I would click the forward/back buttons by accident. Fortunately kensington offers software to allow you to configure the buttons on the K64390. This was a selling feature that caused me to buy the K72370 that is offered on this page.
Summary: This would be a really good mouse if the buttons actually clicked (or something similar) - the buttons feel mushy, and the amount of force varies depending on exactly where you push. On the other hand, the size is really great, and the shape is ergonomically good. So it's a terrific pointing device with buttons that suck.
Summary: I have another Kingston mouse and thought this one would be a good tool to use due to its shape (the other is more for travel). At first the mouse worked well, but soon I noticed that the cursor 'jumped' for no apparent reason. Also, it is very slow to connect to my laptop. Sometimes it is necessary to unplug the USB and re-insert it to make a connection. My other Kingston is a bluetooth device with no connectivity problms or 'dancing cursors'.
