Review on 💻 Adesso WKB-3150UB - Wireless Ergonomic Keyboard with Trackball and Scroll Wheel, Split Key, Long Battery Life, Compact and Portable - Compatible for Laptop/Desktop/PC, Windows XP/7/8/10 by Jill Bell

I bought this keyboard specifically to use while sitting in my Lazy Boy recliner chair. After 4 days of use I got used to it completely and it feels pretty good! About 10 years ago I found that sitting upright at my desk all day made my shoulders and neck get too tight, so I threw away my desk and set up my home office around a lounge chair (with monitors that looked like this were positioned forward). and page). The idea behind the lying position is to completely relax your back, neck, arms and shoulders; and so i work with the keyboard on my lap and the mouse on a small table to the right of the chair. However, there is a problem; I sustained a painful repetitive strain injury in my right shoulder while raising my arm to control a mouse. In other words, when my hands are on the keyboard (using touch typing), the weight of my arms is supported by the armrests of the chair, and therefore there is no load on my shoulders; But every time I use a mouse, I am aggravating a repetitive strain injury I developed in my right shoulder. And that's why I was looking for a keyboard with built-in cursor control so that I could at least keep both hands on the keyboard and both elbows on the armrests most of the time. After trying many keyboards with built-in mouse pads that didn't work, I settled on the ergonomically designed Adesso WKB-3150UB with built-in trackball and scroll wheel. To be honest I'm surprised this thing works so well considering how unergonomic things have gotten. At least it seems to have some very good key design elements that I would say someone on the design team must have had some sense of, although there are still some flaws. First off, this is a great ergonomic keyboard. The angle in all three dimensions is perfectly aligned with my fingertips as my hands converge to meet the keyboard's main row. Each key hits exactly where you'd expect and I have no problem hitting the thing without even paying attention to where the keys are (i.e. 100% blind input). Also important is the shape, feel, and contours of the key surfaces, which are slightly textured and concave, giving an inherent tactile feel to the center of each key. While I know Adesso didn't invent these features, at least they're smart enough to incorporate them! After setting the pointer speed (Control Panel/Mouse Properties) I have no problem controlling the mouse pointer with the trackball. I set my pointer speed to around 40% and enabled "Increase pointer precision", which appears fast enough to move across the screen and slow enough to make precise movements. If necessary, I control the trackball and buttons separately with two hands, so that I can position the pointer very precisely when making a selection, as well as conveniently using drag and drop, etc. Otherwise, one-handed technique can be used less skill is required. It's important to note that the pointer buttons are raised and slightly textured, so finding them by touching (not looking) is practically not a problem, although there's some room for improvement in this area. As I mentioned above, I work on the keyboard from my knees. I'm sure I'm not the only one doing this as I know a lot of people use the keyboard with their TVs etc. While this is in no way optimized for use on "laptops", it is possible that Adesso considers this as a criteria design for future product development. The real innovation of this product is the integrated scroll wheel, it's awesome! I consider the scroll wheel an integral part of any pointing device. Without this feature, I would still take my hands off the keyboard to use the scroll wheel on the mouse. By the way, Windows has no problem with multiple wireless keyboards and pointing devices installed at the same time, so using a regular mouse as an alternative can come in handy when needed. The only downside I've noticed now (after a few days of use) is that it feels too compact around the outer edges. For example, the palm rest might be a bit small, but that's actually not a big deal. Aesthetically, the body of the device feels a bit plasticky and square, which is probably why the buttons are a bit noisy. There are no microswitches, the keys are operated by membrane switches that produce no sound when touched. So the noise coming off the keys seems to be just the result of the clumsy mechanical nature of each key hitting the top and bottom stops and the resonance of the plastic frame they're mounted in. What about efficiency? Because of the great keyboard layout, my text editing and typing speed is much faster. Pointer manipulation might not be as quick as using a mouse, but a small trackball really isn't that bad for speed, especially since you can predictably move it end-to-end across the screen. The real test for me will be whether I can finally heal a repetitive strain injury in my right shoulder, which will likely take time. But so far I've actually had less pain because I keep my shoulders more relaxed by keeping my hands on the keyboard most of the time. Update: I just noticed that the scroll wheel only works 50% of the time; this. A dead center occurs after every second discharge stick. This is not a manufacturing defect but a design defect. It is unforgivable how such a product could go into production with such a glaring defect. I'm deducting two stars and will most likely be back.
