The keyboard does take time to get used to. If you have a home computer and a work computer, I strongly recommend you replace your work keyboard with this style too. I found it too hard to adapt to two different keyboard styles each day ... at work and then switched to this at home. "In my experience, MTBF is roughly 2-3 years (Mean time between failures). I recently replaced my current one which failed after 18 months. Not surprising, since I banged on it for hours every day for work and home, due to covid. This is my 4th purchase of the keyboard, and I bought a backup too, for when this one goes. I've never experienced the lag the other reviewer complained about, however, I also have an Intel-i7 powered PC with 16Gb of memory.

I bought this keyboard hoping to get an awesome typing experience, due to the way it's shaped and all.

It's been a month now and I am utterly disappointed. The keyboard lags every few seconds. Keystrokes don't take effect until about 5secs later. At first I thought it was a driver issue, but I updated the drivers and it started happening again. I used it on both ubuntu and windows, and I experience the same problem. How am I supposed to work effectively with a malfunctioning keyboard? I would have returned it, but I had already ripped the packaging.

It's useless.

Very good Ergo controls etc.

No light to say if the "Caps lock" is on or not. Our system at work needs it ON for certain functions and OFF for others, so maybe it's just me. It's not you, it's me. Also, the little "height adjusters" on the back tend to break after you go "Full Hulk Smash" on the keyboard. Jus' sayin'.

Great units. I just need to replace them now. Ahem.

Excellent range when receiver is above the level of the devices, ergo design is decent enough so it it comfortable to type on for extended periods.

Keyboard is a little on the noisy side for a non mechanical keyboard. Comes with cheap batteries that don't last. Device range is extremely poor when the receiver is below the level of the devices. Mouse shape is uncomfortable for my hand/wrist for extended use.

With my computer below my desk, I had to use the extender cable to raise the height of the receiver to about 1ft above the level of the keyboard and mouse in order to get a strong signal to the receiver, no issues with range after that. Been using for 18 months now, only glaring issue is range when receiver is below device height. The mouse only sees periodic use on another computer, I bought this set for the keyboard alone, use it with a wireless Trackman M570.
