Kensington Expert Wireless Trackball Mouse (K72359WW)

Love the feel of the trackball. Wish the angle was flatter. It kinks my wrist and causes pain that a trackball was supposed to eliminate. Ended up having to angle the housing flat, and then creating a pad for my forearm. After several months of use, my updated review: I bought this trackball hoping it would work out. But sadly, it has not. The ball is large, easy to move, love have 4 buttons and scroll wheel. Those features I have zero problems with. I even like the software, easy to use and allows programming of the buttons. My biggest complaint is with the angle they made. A trackball is supposed to be an ergonomic tool and allow the hand and wrist to remain in a natural neutral position. This is anything but that. Even using the supplied "wrist pad" the angle is in the completely wrong direction for the tool. I have had to resort to stuffing bubble wrap under the housing to get then angle up and then placing a bubble wrap forearm pad the level my arm . I have been using this in this configuration for months and am finally just getting tired of this. I spent good money hoping this would help my hand after using a mouse for 30 years running CAD systems. If Kensington just made the angle go in the opposite direction, this would be the best out there. Whoever was the lead design engineer on this product should be fired for angling this in the completely wrong direction.

You buy a trackball - its like buying a mouse, right? Plug and play. Even wireless. Oh, dont be so droll. Kensington has finally micro-managed itself into the pit of ineptitude from which I fear there is no escape. They may be on their final downhill slide. I own Kensington products. Ive purchased trackballs from them since the 1980s. Yes. Perhaps since they started making them. All with a cord. All very happy. And why not? They did everything right. But I was feeling sporty and modern. I generally dont like wireless devices as they occasionally exhibit a finicky side I dont enjoy in computer work. But this setup may have benefited from a wireless device. I was so stupid. Plug it in. Yes it works slowly. Kensington USED TO include the drivers. Nope. Not anymore. Those days are gone. No matter, I have other trackballs - ill use THAT copy of drivers. Nope. Cant recognize it. Go get the LATEST driver, you stupid customer. Okay, Ill do that soon. Then i notice the wireless is inferior. Yes, its without a wire, but no, the reception makes it unusable. Its only line of sight. It may as well be an old infrared unit. Line of sight works great. Behind anything at all (including flowers), it skips, stutters, and pauses. Worthless. Far below what I once thought was Kensington quality. New batteries? Nope. No change. Still a mess. Okay, lets do the driver thing. Downloaded -- a bit of an unfriendly chore by itself -- and install. But wouldnt you know it?? "This version of Windows requires a digitally signed driver." (W7) Cant use it. Its their driver, off their site, d/l this very day, but theyre apparently not trustworthy enough for windows to work. Now, of course, the device doesnt work at all -- after 2 more reboots and tweaks - what with Windows having isolated the driver and even warning me about it. Its going back. The reception is rubbish. The software is insane -- and thats good ol W7 and it STILL wont work. Kensington has jumped the shark. They no longer make products for people to use, but simply bait for fish to bite on. It SHOULD have been 1. plug and play. 2. exceptional reception. 3. no-glitch software. 4. a happy-to-give-you-the-drivers-we-require website. If youre looking for any of this, do not buy the wireless version. Do not buy from Kensington. Love my other Kensington trackballs.

I generally dont return stuff I buy from Amazon, but I returned this. The scroll ring on this thing is atrocious. It is stiff, scratchy, and devoid of any sort of consistency or feedback. Sometimes it will move with slight pressure, sometimes you have to really put some force behind it. At first I though, I bet this thing has a bearing of some sort. Maybe I just need to tweak it a bit. But then I decided that for the $88 that I payed for it, I expect an office product that does not require disassembly and adjustment right out of the box. Actually I take back the inconsistency remark. That scroll wheel is consistently terrible.

ok, so looking at this mouse you would think its got a great build quality. When I received it the first thing I noticed when using the ball was that it made so much noise. It is not smooth feeling at all and the noise it makes will drive you crazy. Then I realized the ball just pops out. It does not seem to fit properly in its plastic housing so it feels loose and cheap. The ring around the ball does not feel good either. It feels loose and like it will come apart eventually. Since I was unsatisfied with how the whole mouse felt I ended up returning it. Definitely not worth the money they want for this. I am saving you time and money letting you know this as I dont normally leave a review on items I purchase. Look for something better.

I am finding the same problems as others who wrote negative reviews. From the first moment I tried the scroll wheel it felt like a product made in someones garage. Unacceptably poor feel as the wheel jiggles and moves without a professional level of precision and predicatability. Im actually quite shocked. I called Kensington and support wants me to send photos but I see no damage so I came here and saw others have the noted the same. I also agree with those who say the angle is not very comfortable. It should be angled more up to relieve strain on the wrist. Isnt that why were using a trackpad? Other than the shocking scroll wheel the build quality seems very good. I was pleased at how quickly I was able to get someone on the phone from Kensington, so thats a plus. Nonetheless, I hope others dont make the mistake of buying this product.
