Lofree Edge｜485g Weight & Ultra Thin Low-Profile Keyboard 

The flow has more consistent sound in every key.

LE looks really beautiful and masculine. However, I personally prefer the sound on the LF version The video you made is very thoughtful, very relaxing to watch

3:42 スイッチはどうやって分解されましたか？スプリングを軽いものに交換できるなら買いたいと思っています

Flow sounds better. Edge has too much of a high pitch sound and makes it sound cheaper.
