Adesso WKB-3150UB - Wireless Ergonomic Keyboard with Built-in Removable Trackball and Scroll Wheel, Split Key, Long Battery Life, Small and Portable -Compatible for Laptop/Desktop/PC/Windows XP/7/8/10

Been through many keyboards, large, small, usb, wireless, ergonomic, standard, etc. And this wireless, Adesso 3150 fits me perfectly. Have been using it exclusively for the last couple of years. I may have to sit at my computer 8 to 10 hours a day and if I have to continually go back and forth with my arm from the keyboard to a mouse, my arm is pretty worn out by the end of the day. But with the layout of this Adesso, I barely have to move my arm/hand to type, scroll, select, and click. I scroll simply by keeping my hands in the "home" position and using either thumb. If the application I'm using requires and lot of scrolling and moving the screen "cursor" a lot, e.g., the internet (Amazon, etc.), I'll keep my left hand in the "home" position and move my right hand down about an inch to use the trackball with my middle finger, left click with my forefinger, and right click with my fourth finger. All in all very little, if any, movement at all of my left arm and only minimal movement of my right arm. It's quiet and comfortable for as long as I'm using it. No other keyboard that I've tried (many) or viewed comes even close to matching this Adesso 3150 with respect to these ergonomic features. And that includes other offerings from Adesso. The two Triple A batteries required may last anywhere from 4 to 10 months from my experience. I never turn the keyboard off unless changing the batteries or cleaning the trackball (which I may do once a year). I like a steeper slant to the keyboard and purchased an ESC Flip Keyboard stand which I attached to the keyboard bottom that provides this. Initially, the track ball is not quite as responsive as a mouse but with use, it comes to match it. All in all, I recommend it highly.

There will be several caveats to my five-star rating, but when you have suffered as long as I have and tried as many products as I, it deserves five stars. It is tiny, wireless, easy to set aside, uses only one USB slot, and has greatly improved my ergonomic situation. It took me about two weeks to adjust to the new movements. After three weeks I tried to go back to the separate mouse (just to see), and right away realized how much better a built-in roller ball is! Caveats: I wish it had 2 more inches in the split (I have big arms and 2" wider would give me more comfort). I wish the wrist rest were 2 inches deeper. Toss the batteries it comes with - they are crap - install name brand. It is missing the 10 key. I use that all the time in my line of work, but it has been worth it to retrain myself to use the number keys on the keyboard. Not only does it make the device smaller, but it keeps me from, yet again, lifting my hands away from the keyboard.

So first off... this keyboard made my hands feel so much better. I am a computer engineer and I spent 8+ hrs/day on a keyboard/mouse. I was getting pains in my hands, wrists and elbows so severe that I couldn't sleep at night. This keyboard/mouse has almost completely eliminated that pain. Some other things I noted: The mouse buttons are too small. Need to make them bigger. The angle you move to hit the mouse buttons, puts you slightly to the left or right of the mouse buttons and I find myself missing them quite often. The key press (keyboard) isn't very solid. Sometimes you have to mash on keys to get them to register, sometimes a light touch will do. Backspace seems pretty bad about this and is a very used key. Maybe it will get better as I break it in. The keyboard is more compact than normal keyboards so it's harder to get used to. But it's also great because it doesn't take up as much room. (you could throw it in your computer bag along with your laptop if you needed to) Selection (ctrl + arrow, shift + end/home) works correctly. Most new microsoft and hp keyboards do not because they are cheap junk. So you might have to get used to that being a little different. Overall, still getting used to it, but really liking that my hands aren't hurting anymore. EDIT: Purchased this in March, it is now end of August. So I'm updating my review: 1) When the buttons start to wear out, you can barely click the left mouse button. You have to click almost at the bottom of keyboard and half the time it still won't click so I'm smashing the button to get it to work... super annoying. 2) I literally have to smash the keys to get them to type now. This was a problem originally and it only got worse... or my fingers just can't type that fricken hard all the time. Results it a lot of missed keys and has become really annoying. 3) Definitely not worth $60, way over priced. 5 months and I'm already looking for a new keyboard because I'm sick of having to SMASH everything when I type. 4) Put the page up and page down buttons ABOVE the Home and End buttons. I'm always hitting the wrong one, It doesn't make sense to separate them. The only good thing about this product is the roller ball.

This one is a small but functional keyboard, that does its job well. Though, trackball appeared to be no so useful, it's too small and sensitive, and located too low from the finger position, thus if you'd force yourself to use this trackball instead of using it naturally. Also, it feels very much when standing that there is a lack of soft stand for wrists. In summary, this keyboard is interesting as a small ergonomic one with a nice trackball feature for the table lacking space.

This is a very good keyboard & trackball solution. The keyboard is good quality - the keys are light, soft, don't wobble or make undue noise. The lettering is large, high contrast and easy to see. The trackball is very smooth and removable for cleaning. The scroll wheel is a very nice touch. Overall, I am very satisfied. Although the keyboard is a bit expensive, I still feel it's good value for money. I cannot comment about durability yet, as I've only had it for a few weeks. My only minor gripe is that the keyboard is using standard AAA batteries and has no built-in possibilities for recharging. But this is only a minor point. It does have a good life on one set of decent batteries (not the ones that come with it - those are rubbish). EDIT 4 months later: no issues with durability so far. Battery life is amazing! Still using the same pair of batteries that I put in four months ago, and I am using this keyboard at least five days a week! This keyboard may not be for everyone, but it works for me so well that I'm just about to order another because I found myself carrying it around to every computer that I use.

J AI MIS 4 ETOILE POUR QUE MON COMMENTAIRE APPARAISSE MAIS VRAIMENT DECU.

MEME PAS ENCORE ESSAYER DU COUP. ARNAQUE VUE LE PRIX REEL DU PRODUIT

This keyboard is full of small irritant points while you get acquainted to it. I will NOT be love at first sight. However, it's the only one I could find with a pointing device arranged in a way that I could type and use the mouse without having to continually change my position. So I decided to give it a try, and spend some "quality time" together to "build the relationship". The first times the experience was really bad: really hard to use the trackball, too fast and too little dexterity on my thumb. There was definitely an annoying learning curve, and have to try many things before I could find comfort with it. It's been some weeks, I'm not completely done taming this one... but I feel that patience is paying off: I can now sit in a comfortable position - whether it is on a chair, or in lotus/seiza (japanese sitting) positions - and type for hours with my whole body in a relaxed and natural position. This makes my overall energy, mood and disposition improve. If you are a patient person, I strongly recommend this one. But if you are looking for instant gratification, this is probably not your best bet. Some adjustments that I had to do, to find comfort with this keyboard: - The keyboard used to slide down my lap in some positions. I had to apply some gaffers tape to give it more grip. - I had to down the mouse speed at the beginning, to find comfort with the trackball. Now it's back to normal speed. At first your body will tend to tense because of the lack of familiarity with the trackball, but with time you will start to find ease (ex: relax your shoulders and use your whole arm more naturally, and not just your thumb)

Loved the size and weight. But need to adjust to small size. Keys are closer together
