I've been using ergonomic keyboards for the past 23 years. This by far is my favourite in the current market. The unit is one piece so it doesn't have a removable wrist pad which really works well with the design. The wrist pad is not made of fabric and can easily be wiped down which is great for keeping it clean/germs and ongoing use of the device. There are 3 different levels the keyboard can be adjusted to for comfort. The unit uses a unifying Logitech USB so if you already have another Logitech mouse connected, you can just add the device using Logitech options software. Comes with an on/off switch at the top of the keyboard, slightly underneath the lip so it wasn't obvious to me where it was. If you have used many logitech keyboards, you will be extremely pleased with this and if you are using a competitors ergonomic keyboard it is worth the switch. If they had this available in Covid WFH era, I would've purchased 2.
