Bluetooth Trackball Mouse, Jelly Comb 2.4G USB Wireless & Bluetooth Ergonomic Mice Rechargeable with USB-C Port and 3 DPI for Computer Laptop Tablet Phone Mac iPad

The Jelly Comb works perfectly and comfortable for me, with added features to my previous trackballs. I prefer to use trackballs ever since I used the original wired Microsoft trackball.The Jelly Comb has a few major advantages over my Logitech's M570 trackballs, I use with my laptops. The Logitech's are wireless only and work with a USB dongle, taking away a USB socket. The Jelly Comb has Bluetooth, so can be connected to a Bluetooth device without using the dongle, freeing up a socket. The Jelly Comb can be connected to multiple devices in different ways. The sensitivity button is useful for on the fly changes, without having to go into menus to make changes. No need to download and install software. The rechargeable battery has it's advantages, but also disadvantages. Comparing with my Logitech's, they have a long battery life of well over a year or more, depending on the battery fitted! The Jelly Comb manual says it will last a month between charges. Rechargeable batteries have life cycle of charges, so hopefully last many years.The shape of the trackball is the same as the Logitech M570, and so I already knew it would be comfortable. Actually balls are the same size, so are interchangeable and work fine in both trackballs. Maintenance and cleaning is straight forward and important.Read the manual to understand the connection modes. Bluetooth mode is '2' for pairing and use!I recommend the Jelly Comb trackball.

After many years of using the old wired Kensington Orbits, I'm a confirmed trackball user. Having just acquired a bluetooth keyboard, I was intrigued by the idea of a wireless trackball, but really wanted bluetooth connectivity to allow the option of using with a tablet. The reviews of the Jelly Comb, plus the option to connect to multiple devices and the very reasonable price made it the best choice, although I wasn't sure about the thumb operated ball. I'm still getting used to that after the finger ball and thumb click of the Orbit, but I'm really pleased so far. The size is perfect to support my hand and after adjusting the DPI, I'm no longer sending the cursor all over the place.I was disappointed that there were no protective cases linked to the listing, but reviews suggested the Jelly Comb is a very similar profile to the Logitech MX Ergo and checking the dimensions proved it to be slightly narrower and lower while only a couple of mm longer. After viewing photos, I went for the co2CREA case. I'm sure they're all the same size and shape, but the plush lining and the photos suggested there might be some leeway in the fitting. Delighted to report it fits perfectly, so probably they all would. The charging cable also fits either in the top half of the case, or underneath the base, probably due to the slightly lower profile of the Jelly Comb and the plush interior.

I have always wanted a trackball mouse for its egronomics (the wrist doesn't move at all and can be rested on the table, reducing stress) but couldn't get one as most of them come with a dongle to attach to a USB port on the laptop. My laptop's ports are already fully occupied, so this bluetooth version is a god-send. The track-ball works well - smooth and precise movements are possible. The rubber gaskets underneath hold the mouse firmly in place. The buttons are wide spaced and easy to click. Best of all, the battery is rechargeable (over USB-C) so no more worrying over replacement batteries.

Perfect for gaming or just as a very good quality mouse for the PC. The usb is underneath the mouse and once plugged into the pc it was up and running immediately.It's a nice feel soft rubber feel and fits comfortably in my hand. The tracker ball moves really well and looks great with it being a bright contrasting red colour.

This was bought because recently I've been experiencing wrist/shoulder/neck pain after prolonged sessions with an ordinary mouse. I've been using it for over a week now and I have to say once you get used to it (a few hours before it becomes completely natural) it has helped with the various aches and pains. You may well have to adjust the dpi and tracking speed to suit your preferences - would recommend.

The build quality is good. I wouldn't want it to be any heavier, and it does not feel cheap.The unwanted sideways movement another reviewer was talking about just comes down to practice.Ergonomically the mice is also very nice, it forces you to keep your hand in quite a comfortable position.

Purchased this for my wife who was getting shoulder pain using her regular mouse, took a little getting used to, but has had no shoulder pain since and finds it natural to use.

this is great value but it is ultimately a budget product.- Is it as good as a £100+ trackball.. no- is it totally useable? yes!- is it worth the miney yes!
