The keyboard is very easy to type on. It has a nice reaction and is very pleasant to the touch. As someone already wrote here, it's kind of that "notebook style". But the advantages end there. There is a nonsensical WIN/MAC mode switch on the keyboard. I would welcome this as some kind of switch at the back or bottom. The only reasonable justification is if someone is using WIN and MAC at the same time. Plus, the mode key is always lit, which drains the battery faster. Similarly, Caps lock lights up and while it is active, it stays on (for comparison - with the Dell keyboard, caps/num/scroll lock always lights up for a moment after activation and then goes off). Another nonsense is the FN lock disabling. Every time the keyboard reboots, you need to re-enable FN lock or the FN commands below will be executed instead of F1-12. Very irritating! What I also disliked is the width of the left CTRL key, which is very wide. I almost always press the FN key instead of the WIN key. Well, the last shortcoming is the battery life, where thanks to the constantly lit keys, the lifetime is about 2 months with normal use. For me, I rather do not recommend this product.
It's good to write on
Low key stroke
Pleasantly heavy
WIN/MAC key still lit
The battery does not last long
Resetting FN lock
Left CTRL key too wide

I quite like the keyboard, I like the "notebook" keys with low stroke. Except for a little "muddy" grip. The mouse would be fine, too, if it weren't for the absolutely irritating "feature" where you have to press the mouse button to make the cursor appear. I'm thinking of undoing the whole thing, because it drives me crazy to go back to the computer, fiddle with the mouse, and nothing - the cursor is nowhere to be seen before I realize I have to click first: (((
Relatively pleasant keyboard
Mouse. Irritating need to click to wake the mouse from power saving mode
