Ergonomic Split Keyboard With Trackball

This product -- especially when combined with a split ergonomic keyboard -- helps to reduce stress on your wrists. Clutching the mouse puts a lot of stress on the muscles in your forearm. But you roll this big trackball with your open hand. Instead of clutching the mouse button, you can simply tap one of the big programmable buttons with your thumb, and the mouse locks and drags until you tap the button again, when it releases. The scroll wheel is terrific. It seems like an afterthought but I use it all the time. I like this product so much, I bought one for my business partner for Christmas. Just like the split keyboard, people who sit down at my computer and use the trackball for the first time hate it. But if they use it for more than one full day, they end up loving it.

This is a great trackball. I use it between the two halves of a Kinesis Freestyle Pro split keyboard to reduce horizontal arm movement. The front has legs which can be raised to create a flat profile (but not that it sits fairly high in this orientation). Also note that there is no horizontal scroll capability on the scroll wheel if that's important to you. For me, these aren't issues and the huge trackball and click buttons make it very easy to use.

I'm a trackball convert. I was having a lot of wrist pain using my trackpad or mouse. The trackball is very ergonomic for me -- very comfortable and very intuitive. I really like the scrolling ring.

It works exactly as intended. I got a trackball to try and make my environment more ergonomic and avoid RSI. It's too soon to tell if this will be a big improvement in that respect, but as a pointing device, it's fine. The scroll function is fantastic and totally intuitive after about twenty minutes. I have never used a trackball. It's taken about a week to get back most of my accuracy with a mouse, but I'm also 47 years old and that's to be expected. Some reviews complain about the buttons. They work fine and don't feel especially Cheap. The accurate mode is interesting, but I have an intuos tablet for fine work in Photoshop and other design programs, so it's more of a novetly for me. The software works well. I had to mess with the acceleration a little bit (27 mac monitor), but that's to be expected. I'm tempted to fire up Call of Duty and see how badly I do on it! Overall, if you want a finger ball, this one is well-made with good software. It won't replace an emotional void in your life, but as a piece of hardware it's great.

I've been using Kensington trackballs for many years. This is a very ergonomic and sexy-looking one. Also, Kensington has updated their Trackball Works software so it's flawless and quick on Apple's latest Yosemite OS X 10.10.1. B&H Photo offered the best net price.

It is the only compact ergonomic keyboard that seems to be available, that is structurally sound (without bending).

My shipwent went missing, but was replaced likety-split! Impressed with that, as well as the ergonomic and wfficient battery charger for my camera!

I've been using the Microsoft Natural Ergonomic Keyboard (4000?) for years. I've found that I need to see the keys more often and thought the old keyboard quite large. While looking for low-vision keyboards I found this illuminated model. I thought I'd never adapt to or like a flat keyboard like this but I was so wrong. This is the best keyboard I've ever used. Easy strike, silent, and I can see the keys without bright room lighting -- even without my glasses! A full numbers layout, easy extra function keys, great configuration, easy setup, and a sophisticated appearance. Love it. Highly recommended for everyone at all skill levels.
