Very happy with my choice of keyboard (love the Gateron blue switches) and speed of process and delivery. Thought I had an issue with the keyboard mapping but as it turned out was a PICNIC (i.e. my fault) not swapping out some of the keys for the and @, etc. Initially called support who were busy so left a message. Impressed that someone called me back about 30 mins later so good customer service and aftercare so far. The keyboard itself is mint but didn't realise from the descriptionspec how high from the desk 15mm can be so ordered the Keychron wooden palm rest (no Carpell Tunnel for me!!). Only suggestion for the website would be to see if you could accept Apple (or Google) pay as more secure and easy as my delivery address gets added automatically instead of manually typing it out on the online order form.

Order arrived as described and on-time.

The keyboard itself working perfectly, it's a bit loud on the bright side, so some dampening material inside the body may help. Keychron (the company) should really consider adding dampening material as a built-in feature for this line of keyboards.

Works great, the keys have a really nice finish to them and the different RGB modes are fun to mess around with. You can be connected to 3 devices at the same time which makes it really seamless to work between machines and I've not had any problems with connection drops yet
