ELECOMRelacon Handheld Trackball Mouse, Thumb Control, 2.4GHz Wireless, Ergonomic Design, 10-Button Function with Smooth Tracking, Windows11, MacOS (M-RT1DRBK)

I can't really recommend the bluetooth version of this thing.Bluetooth hasn't been implemented very well and you'll notice this when trying to pair it with your device. While in pairing mode, it may not even show up. If it does, it can still be a struggle to pair. you basically just have to wait 10 seconds between failed pairing attempts to get it to work (Windows 11 PC).Here are my results when trying to pair it:Desktop PC (Zoom USB dongle) - Can't even discover itSurface Book Pro (Integrated bluetooth) - paired after multiple attempts. Now works normally.Android device - Paired, no issues.MacBook - Paired even though it threw an error.As for the functionality, it has an interesting mix of being well built but seemingly flimsy at the same time.Make no mistake, it is well built, but the ball, despite being held in by a tiny ball-point pen type clip, sits a bit loosely in the socket. This makes it rattle a bit when jostled.My hands are slightly too large for this thing to feel really ergonomic, but it still has a decent enough feel to it. The buttons are a bit high angled so I fear I might drop it when trying to perform a click. (this is because I have to shift my grip a bit so I can comfortably reach the button while keeping my thumb on the track ball.)[update, upgraded to 5 stars]Ok, the WiFi version works great.I have a computer dedicated to media (It's set up as a kiosk to a plex client) and this mouse is the perfect remote control for it.All the controls can be done using one hand without needing a surface and the trackball is easy enough that I don't need to enable accessibility settings on the PC to be able to accurately click on links.In addition to this, there is a scroll wheel, forward/back buttons, lateral scrolling and media buttons (next, previous, play/pause, vol+/vol-)Lastly, it even has a power switch so that I can simply turn it off and not have to worry about bumping it when I'm watching a movie with the family. It's everything I want out of a remote control for a media center client.

First I noticed a terrible delay on the volume up/down button (connected to Windows). Now the trackball doesnt work either. Intermittently one or the other will work for awhile. Not a distance/range or battery issue. Overpriced, feels cheap. The trackball works ok, but loses contact if you tilt either direction past 45 deg. The trackball rattles too.I felt it was overpriced but enjoyed using it for increasing/decreasing volume from 10 ft away, or sometimes making a simple adjustment with the trackball. (its no good for any precise work) Now that it is intermittently failing, I regret wasting money on it. ---> Try the Kensington Orbit instead!edit 7-13-24It's been working normally. I think the issue was related to interference from another 2.4 usb device. Needs further testing. This product works well. The buttons could be better. Price is fair I think based on the overall reliability so far. Thanks for developing this. We need more devices like this, and more feedback on them so they can keep improving!

I switched to using a thumb trackball mouse from a logical technology company years ago. I was happy with it until recently when wrist aches made me turn back to the idea of a handheld trackball mouse. Previously I had tried a couple different units that featured a tiny, green trackball. Both units felt like junk and operated even worse.This time I was specifically looking for a bluetooth handheld trackball mouse so I didn't need a dongle tying up a USB slot on my laptop all the time. This Elecom unit turned out to be precisely what I was looking for.I am delighted with the functionality and features. The build quality feels on par with any logical technology trackball mouse and the performance merits the price. Initial setup was easy enough (despite foreign language instructions) and now when I turn it on, it connects to my laptop almost instantly.I'm happy with all the default button functions. I have smaller hands and find the device comfortable and easy to use. The tracking is spot on and I've been able to use it for work and play without issue. This mouse has several more buttons than I had before and I'm finding them all quite useful.I like that it uses AAA batteries as opposed to a built-in rechargeable. I'd rather swap out a couple batteries every 8 months than have to plug it in and wait. Not to mention I can pull the batteries for long term storage, if necessary. Also, those rechargeable batteries can only charge so many times before they fail, and good luck finding a replacement when it does. Alkalines for the win! Same goes for gasoline... But I digress.It's a great mouse, it's got a lot of features, seems of adequate quality, and is well worth the asking price. I read a complaint about the ball moving when the mouse is tilted to the side. I notice the slight movement as mentioned, but it has no impact on performance and I can use the mouse at almost any angle my hand can hold it without a problem. Holding it upside down, the ball will rise slightly before functioning as normal, but why on earth would you hold it upside down?Also worthy of note is that I can have the mouse and my headphones both connected to my laptop simultaneously without any issues. I cannot connect both my headphones and a bluetooth gamepad at the same time without problems, so I was concerned about that when I ordered this mouse.
