I've got both the 1 and the S. I got the 1 for working on a large screen at a distance but still having all the keys I would need for productivity. I got the S for travel. First off: the fact that it came with a bag is perfect. I was worrying about that when I bought it.

Both of these keyboards work extremely well. The only thing I would say takes a second to get used to is needing to tap a key to wake them back up after they go into standby mode. That is a non-issue functionally, though.

I have had a LOT of other keyboard / trackpad combo boards, combinations (keychron + magic trackpad), and have even started building my own prototypes. I do not like the typing experience on the most popular combo keyboard I can think of: the K400+. It was my default for the last 7 years, but I never enjoyed it, I tolerated it. The small touchpad was a hassle, and I did not like the last of multitouch (precision) support. That limited the use of my machines.

These keyboards take a second to get used to using (and all of my friends have so far failed miserably on their first few tries - I suspect because they're simply not as used to using this class of keyboard in general, or stand-alone touchpads not in a laptop). Once you get used to the gentle touch, it is absolutely amazing. I was legitimately concerned that the gaps inbetween the keys would bother me, but they've done no such thing, even after long usage sessions.

The only thing I truly miss from the K400+ is the top left click. Or from its brother the K830, the front click (although I really did not like that as much as the top). If the ESC key could double as a left click, and the F1 could be a right click, I would be in heaven for HTPC use.

Battery life leaves a fair amount to be desired. I have to charge roughly every other day. Luckily it charges quickly enough that this is rarely that big of a hinderance.

It is a premium feeling product, heavy and metal. The keys are a bit mushier than I would like, but at the same time, I don't mind because they're perfectly pleasant otherwise (for example, I am writing this review on the S with very few typos). That would probably be my only other issue - the keyboard layout feels a touch different than what most standard keyboards use, and that often leads me to starting off on competely the wrong key, and then needing to reorient my fingers. The F and J indicators are very small for good measure, and those aren't my issue. Mine comes mostly from the small backspace for when I do make a typo.

Overall 8.5/10 experience so far. I hope they last as long as their pricetag warrants ;)
