Sehr Zufrieden

Ich habe mir mit dem Lemokey mein erstes Iso DE Barebone geholt. Hauptgrund für den Kauf war das Alugehäuse, der linksbündig Knopf und Hotswap. Bonusfeatures waren die LEDs, VIA oder auch die Funkfunktion.
Das Keyboard nutze ich mit Brown tactil box switches und steelseries keycaps. Der Sound war hierbei schon ohne Eingriff in das Gehäuse, für mich, sehr zufrieden stellend. Für mobile Nutzung ungeeignet, da es doch sehr schwere ist - daher nur am Desktop PC Zuhause in Nutzung.

Nice premium barebone

I've bought the L3 as a barebone in ISO layout.
The stock board is really nice and heavy (no sliding on the desk).
The only mod I did to the case was the force break, since it was a little bit pingy.
All in all it's my new daily driver and I'm really happy with it.

Very Good, but dissasembly a bit difficult

I like the keyboard very much. Good sound, good feel, good heft, good keycaps, good knob. In the video provided by Keychron/Lemokey all the plates just magically came off after removing the screws that hold them down, that was not my experience. The big plate required quite some prying with my fingers, the one that is under the macro keys came of quite easily, yet certainly not as easily as in the video. The one that is under the knob was stuck like glue, the way i solved it was to place the smaller of the allan keys in one of the screw hole and exert upwards force, since there was way to pry it up without damaging the finish on the product. It took close to 10 minutes of trying to get the plate that is under the knob off.

I like it very much, my last keyboard was a IQUNIX F97. Lemokey L3 Sounds better, feels better, has programmable key, has VIA/QMK. Overall a better keyboard. The disassembly should not be done too many times for fear of harming finish of the product. Infinitely better than some gaming keyboards that I have had in the past. VIA does not recognize that the particular keyboard that I have is a Nordic ISO variant, and defaults to US ANSI. I have not yet found a way to change it to Nordic ISO in VIA. I find that the amount of on keyboard storage is quite lacking, a single macro filled up close to 15% of the entire storage(not a particularly long and complex macro). I fixed this by simply remapping the keys(which uses close to no space at all)to keys that are not found on the keyboard(Numpad keys, F13 and upwards, etc). And then using AutoHotKey to program the desired macro/behavior.
