I'm delighted with this keyboard. It's a bargain at under 100 quid and would recommend this to anyone. Especially as a first mechanical keyboard.

It was surprisingly good out of the box. Gateron browns are pretty smooth, with a light tactile bump. The stabilisers were quite well lubed from the factory. The bluetooth and RGB functions are good, too. the layout is fairly good and not hard to get used too. The thin keycaps with small legends are the only bit I didn't really like - but that's a preference thing.

It was easy and fun to mod (I would probably leave the battery in place if I did it again. It's hard to unplug and really well stuck down). With a silicone pour, tape mod, lubed switches with o-rings and some cheap PBT keycaps it looks and sounds lovely. Kind of a hard bottom-out, at this price I'm not complaining.

This was a present for my partner and she is very pleased with this. It is exactly what she was looking for and was so pleased to be able to source a UK layout.
Thanks for an excellent product and service.
