FEKER JJK21 Numpad Kit

Honestly this thing is great. The gasket and sound sound thick without lubing or mods, and the structure is pretty solid feeling (this thing weighs like a pound or two lol). I see a lot of people concerned about the automatic sleep mode and how it makes the numpad not register the first click or volume change, but this is only a problem in Bluetooth or 2.4 mode, and when its plugged in (and in OFF mode) its constantly on. Granted, it automatically turning off is a bit of an issue even if its only in non-wired mode, but the other upsides make up for this tiny blip.

The software is being blocked by Windows.

This numpad has been one of my favorite recent purchases. The wireless is very snappy and painless to pair. I use it to pull out when I need to enter a lot of numbers for work but then put it away for playing games. Its a great little addition and it even has surprisingly solid gasket performance and the stabilizers on mine are very solid.

Even when wired the keypad will go to sleep and not send the first key press. It makes using it almost impossible as there is a big risk the data you are entering will be incorrect unless you are carefully watching every time you use it.

Even full keyboards at half the cost of this keypad send the first key press.

キーを打つ度にドンドンと机を叩くような低い音が響くので、柔らかいリストレストの上に置いて使っています。
ライティングの設定は、しばらく続けるとなぜか変更を受け付けなくなるので、その度にリセット(多分Fn+Esc長押し)を押しています。
Windowsを起動した直後にpinを入れるためにキーを押しても反応が鈍く、入力をやり直す機会が増えたことも不満です。
追記
接続は、PC側もUSB-Cで繋ぐと安定しました。
ライティングを点滅させるとNumランプも一緒に点滅するので視認性が悪いです。
ライティングはFN+NUMで消灯できますが、PCの電源を入れる度に点灯状態に戻ります。
スタビライザーやガスケットはよいと思っただけに残念です。
