X9 Performance Ergonomic Wireless Keyboard with Trackball, Rechargeable, Backlight, Built-in Mouse Buttons, 2.4G Split Keyboard, Wireless for Windows PC and Chrome

Costly but good.

Having it for few months now and it works very well.. took me time to get used to the trackball position but it significantly reduced mouse reaching movement. very helpful once you get used to the track ball position.

It seems good quality so far. I bought it because I wanted to have an ergonomics keyboard that allows me to code without having to grab a mouse every 2 seconds to move the cursor or scroll the code. At first I couldn't figure out why I was having such a hard time using the trackball and buttons (I find the use of trackpad and buttons on my laptop quite efficient) until I realised the buttons were at the top and the ball below. Seriously a huge design flaw and makes clicking much harder as I have to reach over the ball to click it and end up moving the pointer. Just made the whole experience really awful tbh. And to think I spent so much money on it because I couldn't find a good alternative elsewhere.

I BUY IT AND I LIKE D IT IN WORK.

Keyboard works well. Still getting used to the keys and trackball mouse. The keys are 'soft' and the spacing is different to my other ergonomic keyboard. The trackball is small, so takes a lot of scrolling to get from one monitor to the next. Have found I still need to use a traditional mouse for a lot of work but it's handy to have an alternative when my back and shoulders need a rest from stretching with the traditional mouse. Am happy with the purchase

I bought this because I specifically needed a true ergonomic option that eliminates the need for even minimal arm movement to reach a nearby mouse, and it fits the purpose completely. It is much more affordable than newer, fully split options, and far easier to use if you aren't always sitting at a desk—such as in bed after an injury, on the sofa, or using a large TV screen. It has a sturdy design with good materials. I had read plenty of reviews beforehand and adjusted my expectations, so while it doesn't have the premium feel I would expect at this price range, it is still very good regardless. The keys are well-responsive. I managed to rely on it fully right after unpacking, using the wheel and trackball instead of a mouse. I was expecting more difficulty with the learning curve; it is smooth, but it slowed me down a bit, though it is improving day by day. The arm and palm position is comfortable; I instantly felt the difference and managed longer stretches without the usual wrist fatigue, even if I am slowed down for now given the new layout. The backlight dims quite quickly, though that might just be a settings issue—I haven't had time to fiddle around with the options yet. If key remapping is possible, that would be ideal. I am used to the Delete button on a TKL layout, so the traditional Delete location is actually a bigger obstacle for me at this point than the new split design. What is not so great, especially at this price range, is the RF dongle and the key legends, which look a bit pixelated.

After a great deal of searching I've finally found a keyboard that has all the features Ive been looking for. Wireless, ergonomic, backlit with a trackball all in one package. Sounds easy to find but I can promise you it is not, especially at an affordable price. The only issue Ive run into is the keys sometimes stick down as though something sticky has been spilt on them (which nothing has been). Other than the minor key issue this keyboard is great. It not flashy by any means with only one color option for the backlighting but it is dimmable. The trackball is very responsive and there are several dedicated keys for things such as multimedia controls, email, copilot, file explorer and a few more. It isnt flashy nor fancy kinda like a stamped metal ak-47. It does many things and does them well at a very affordable price.

So far so good! Really happy with the quality of the product and how responsive the ball is, and how quiet the keyboard istoo. This is making it really easy on my hands to be on a keyboard 12+ hours a day.
