Mini Keyboard with Touchpad USB Interface Black KB-540BU (ACK-540U)

I've ordered this thing twice now. Once, three years ago and again about six months ago when I dropped something heavy on the last one and broke it. This is the only keyboard I use for the simple fact that it's much smaller than normal keyboards and that makes it more comfortable to type on, but there are multiple other things I like about it.The keys make a very satisfying noise and aren't too loud for my taste, and the overall design is sleek and easy to use. The only thing I'd change is the scroll pad. I never use it, since I only use it on a PC and I'd rather use a mouse. That being said, I have never once accidentally interacted with the scroll pad, which means it's incredibly well-positioned for staying out of the way when it's not wanted. I'm thankful for the bump of plastic for my wrists to rest on, anyway. When I tested out the scroll pad, it seems to have very low sensitivity (kind of feels like the mouse drags along) but that may be because I'm used to using a mouse.Overall, this is an excellent and long-lasting product. The last one lasted 3+ years. I'd highly recommend it.

This little keyboard with touchpad is inexpensive, easy to use, responsive, and very good value for the money.Larger fingers may find the keyboard a bit small at first, but the size is a real plus on a crowded desk top: about 11.5" x 9". It has small back feet that flip out to put the keyboard at a convenient angle. You plug it into a USB port and it is good to go immediately.The touchpad is a good size and has a scroll function on the right. It is very responsive and quick. A touchpad will really help your arm and shoulder, if you find that clutching and clicking a mouse sends you to the chiropractor. You right & left click with your thumb on the bars below the pad. Just a slight tap with your fingertip is enough to activate many functions on the touchpad, and you can move the cursor at lightning speed. Your keyboard with touchpad can be directly in front of your screen, where your hands and eyes are. The pad and keyboard are close together, so you do not waste time moving around. No mouse to let go of when you want to type, and no mousepad needed. I so much prefer this board to a mouse and keyboard!

I purchased because I have bad shoulders and using a mouse requires too much lateral movement. With this, I keep my hands in one place, no shoulder pain! (ie it is a great ergonometric solution).Easy to learn, is a like a laptop keyboard - but slightly bigger and certainly more solid.Highly recommend also if you are short on desk space.

I love that this is a small keyboard with the numbers across the top vs on the side, which makes it easier to use on your lap. I also like that it has a long cord, since I bought it in order to sit further from my laptop to avoid radiation. However, the touchpad almost never works. I paid significantly more for this keyboard than for a regular one, solely because it has a touchpad, so this was a waste of money.I've tried to make do with it for nearly a year now, but I'm going to have to buy a new one, maybe with a trackball. I find the touch pad works for a few minutes if I've just cleaned it with computer screen cleaner, wiped it dry, then let it go through an additional air dry for 5 minutes. If it's a warm day and my finger tip is even a tiny bit moist, or if I were to actually use hand cream, it stops functioning altogether and needs another 7 minute period of cleaning and air drying. The slightlest moisture or oil on my fingertip completely stops the touchpad from functioning. It's really too bad because I love everything else about the keyboard. I've had the same Dell laptop for 7 years now and it's touchpad never fails, even if I've just applied handcream, so I know some touchpads are reliable and high-quality, but sadly, this one is not.

I've purchased 4 units after my inital purchase years ago to put on every computer I use at home and at work. Like it so much, I purchased this one to have an extra just incase. I have never had any concerns with any of the keyboards. Highly recommend

Not really the hightest quality keyboard. Prefer to pay more and have better product as the keys aren't really the best for typing.

This is by far my favorite keyboard. Every couple of years it needs replacing of course, and I get the same model. Tried many others but this one is the best. Smaller one with a really convenient trackpad built in. I just love it!

Great Quality keyboards @ great price! We love these in our Repair Center!
