Logitech MX620 Cordless Laser Mouse (Black)

I love this mouse, it uses "fast RF" technology, not Bluetooth, to connect to a small USB receiver. The scroll wheel has adjustable firmness, which allows you to either scroll through a couple lines at a time, or through many pages in seconds. The laser for this mouse is invisible, which is good for people who hate the bright red LEDs of optical mice. The mouse worked instantly when connected to my PC running Windows Vista. Optional software can be installed from Logitech to take advantage of various customization choices (button assignments, on-screen battery indicator, etc.). A button on the bottom can be used to turn off the mouse when not in use to conserve battery life. Logitech states the batteries will last for 1 year, and two Duracell AA batteries were included in the package. Nice. A battery indicator LED on the mouse shows when it's time to swap out those cells, which I haven't had to do yet after one month of ownership. I bought this mouse to replace a Microsoft Blutooth mouse that was part of the "MS Optical Desktop Elite for Bluetooth" which was ALWAYS dropping its connection and for which I had to recharge NiMH batteries every few weeks. This mouse was worth every penny, I would highly recommend it to right-handers looking for a simple, elegant mouse that will provide them with many years of happy mousing. EDIT: Here I am in the beginning of September, and the low battery light finally came on! These batteries have been in constant use (maybe 5 hours+ per day) since December 2008. The battery level states that I have 30 days left to replace the AA batteries.

This is one of the best mice I have found to work well on Mac. I've been using Mac now for several years after being a lifelong Windows user. I had been using the Apple bluetooth wireless mice and in general I liked them, but after a while they would start acting up. It would become very difficult to right-click or the scroll ball would get dirty and start sticking. The dirty scroll ball is easy to fix (just clean it) but the right-click issue would really become a problem. I ended up going through probably 4 or 5 of these mice before I decided to ditch it and try something else. I then did some research online and ended up buying quite a few more mice. The first was a Microsoft bluetooth mouse. It took a bit of "hacking" to get it working on Mac but eventually it paired up but I didn't like the performance at all. It was very laggy and unprecise. After more research, I then ordered the bluetooth mouse from Razer. Razer is very well known as the makers of some of the best mice for gaming. Very precise and accurate. But, they are a bit expensive. I ended up ordering two of these based on the great reviews (one for my Mac Pro and one for my laptop). These turned out to indeed be very precise and accurate but they had an irritating trait. If you let it sit still for just a couple seconds (and I mean only 2 or 3 here), when i went to move it again it would have a slight delay in responding and thus the mouse pointer would end up jumping. I found this extremely annoying and made it very difficult to use. I contacted Razer about this and after a few email exchanges and testing on different computers (I tried on a total of 6 different Macs all with the same experience), they told me this was due to it going into a "power saving" mode to make the batteries last longer. I told them this was ridiculous and this should only happen maybe after a couple minutes of sitting still. Not just a couple seconds. They told me they'd bring this up with their engineers. I then decided to give up on bluetooth as nobody seems to make bluetooth mouse that responds well with the exception of Apple but their mice have different issues. So, I then tried a Microsoft wireless mouse that uses a USB dongle instead of bluetooh for wireless communication. This mouse turned out to also have bad delay problems. So, finally I decided to give Logitech a try and ordered this mouse (MX620) from Amazon. The same day I also ended up going to a local big box store and picked up the Logitech VX Revolution Cordless Laser Mouse for Notebooks as it was on sale. The VX Revolution is very similar to this mouse but it is marketed as a "notebook" mouse and is thus a bit smaller. I figured I'd use the VX for my laptop. So, I tried them both. First I tried this mouse from Amazon and it worked great! Very responsive and accurate. No delays. No lag. It was just perfect. I was so relieved to have finally found a decent Mac mouse! I then decided to try the VX Revolution and it worked just as well as this one (MX620). But, I liked it a bit better due to the "feet" on it. They are made out of some kind of very slippery material and it glided much smoother over my hard plastic Everglide mouse pad. The MX620 has feet that aren't quite as "slippery" and thus takes a bit more effort to get it to start moving. The result ended up being that the VX was better for making very small movements. So, I love both the MX620 and the VX Revolution mice. They are both excellent mice for Mac users out there. They also make an Logitech MX Revolution Cordless Laser Mouse which also sounds great (same slippery feet as the VX Revo but is a full size mouse). But, I didn't want to give it a try as it is rechargeable and thus requires a charging base to be on your desk and you have to remember to keep putting the mouse back in the charger. For me, I didn't want the extra desk clutter and yet another power brick to deal with. I'd rather have a mouse that uses normal batteries which these two mice do.

For the most part, this mouse is comfortable to use and has a perfect contour. Its biggest selling point is the mouse wheel - this thing can really scroll a pages-long document in a handful of seconds with a simple flick, saving a lot of strain on your finger. A switch under the mouse will put the wheel in "traditional" wheel mode, where it restrains mouse movement with tick marks (not really sure how else to explain that). I simply installed this mouse directly through Windows - no other software or drivers needed (I'm using Vista Ultimate). Another bonus - this mouse uses a USB stick to receive its signal...no more of those ridiculous USB platforms that you have to make room for on your desk. Battery life is decent - the two AA's will last quite awhile, and I use my mouse constantly on a daily basis. I think I've replaced the batteries every several months. A battery indicator light on the left side of the mouse will let you know when it's time to change the batteries. My biggest gripe with this mouse is that it constantly experiences bouts of non-responsiveness, where the mouse cursor becomes choppy and appears to suffer terribly from skipping. When this happens, the cursor moves sluggishly and it is impossible to target something on the screen, as it jumps and skips to its path, moving at half speed. It almost has the feel of using a mouse on a computer that has used up all of its memory (but that's not the case, I have 8 GB of RAM). At first, I thought it was because one of the batteries was dying out, but the issue persisted even with brand new batteries. This is completely unacceptable and just this one issue is enough to warrant giving the product a bad rating. I am really disappointed with this mouse because of this issue, and am almost compelled to go back to a corded mouse so that I don't have to deal with it again. For the record, I think Logitech makes great products. This one, in my opinion, fell short - and it is a shame, because all of the other great elements were there (contour, USB adapter, fast scrolling, etc.)
