Lofree asserts that its latest product is "extremely thin" compared to the average "all aluminum" mechanical keyboard. Nevertheless, it still accommodates "highly acclaimed" Full POM switches from Kailh that are, moreover, hot-swappable and paired to custom keycap layouts. The Flow also integrates an "innovative" Gasket Mount system and can be used in wired or wireless modes.https://www.notebookcheck.net/Lofree-Flow-launches-as-world-s-first-low-profile-Kalih-Full-POM-switch-mechanical-keyboard.752806.0.html
POM aka Delrin is an interesting material and is indeed self lubricating, should make for good longevity and performance.
Worth noting:
- this keyboard does not support QMK/VIA, so no remapping (e.g. it has weird pgup/pgdown positions and no way to change it in firmware)
- this keyboard does not support switching Fn+F-keys function
No 2.4Gz low latency connection.. that's a dealbreaker
