A: Did you try the small on/off switch on the right side toward the back of the keyboard? I only ask because I did not know it was there and had problems with mine at first. I actually took one back and exchanged it because it would not connect. Now I think it was likely turned off and I didn’t know it.

In a word, excellent. I've had this keyboard and mouse set for almost a year now so I feel I can adequately review it. I’m an IT professional and between work, training pursuits and my own generally nerdiness I spend most of my waking hours parked in front of it. And it has proven to be an excellent companion. I purchased it so I could toggle easily between my work laptop, personal laptop and iPhone and it has performed very well in that capacity. I also wanted a keyboard that employed encryption (it’s shocking how easy it is to hack many wireless keyboards) and this fit the bill for under $80. Under this extreme usage battery life is about ten months, more than adequate in my opinion. Enough about its admirable qualities, what about the downside? Well the mouse has lost connection with one device or another from time to time and had to be re-paired, the keyboard is less prone to this. In all fairness even the most expensive units are susceptible to this. The typing experience is good but not great and some of the mouse buttons can be accidentally activated if you’re not careful. If you need the ultimate in a typing experience, I recommend looking at the MX Keys/MX Master3 mouse combo. One of my coworkers has this setup and it is amazing (albeit at 2.5 times the price I paid). I rarely give anything 5-stars, but I feel for the price point it is deserving in this case. If you take the price out of the equation it knocks it down to 4-stars.

This keyboard has worked just fine over the years, the only downside is not having backlit keys. The mouse has worked without any issues, and the keys have never gotten stuck. Bluetooth pairing is easy and you have the option to pair with 3 different devices. The integrated palm rest is soft enough while typing. This keyboard does have three levels of height adjustment. Likes: Good quality; Bluetooth pairing with multiple devices; soft keys; height adjustment Dislikes: No backlit keys Oh, by the way: There is a Logitect software you can download to make custom adjustments to the keys and mouse.

Keys feel nice, connects to computer with USB-A. Ergonomic, comfortable and adjustable height. Some keys are starting to stick after 2 months of use. Haven't tried the mouse. Keeping as spare.
