What will you mostly use it for?
The Feker JJK21 is the clear choice for most practical applications, winning in office, programming, travel, and content creation due to its numpad layout, wireless features, and programmability.

The two kits tie only in the niche area of modding, where the Reviung 5's through-hole, open-source build offers a distinct experience from the JJK21's more modern, foam-included construction.

“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…”
“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。…”

Feker JJK21 vs KEEBD Reviung 5: your questions
No, it is a DIY kit. You must provide and install your own mechanical switches and keycaps to complete it. The kit does include the PCB, case, plate, stabilizers, foam, battery, cable, and dongle.
The Reviung 5 kit requires significant additional parts. You must source a Pro Micro controller, 4-5 MX switches, 4-5 keycaps, and an optional rotary encoder. The kit only includes the acrylic plates, PCB, diodes, standoffs, screws, and one tactile switch.
The vendor description states it supports Bluetooth and 2.4GHz wireless connectivity. For the 2.4GHz mode, it includes a USB dongle. Its software support is listed for Windows XP through 10.
The Feker JJK21 is likely easier for beginners. It has a hot-swappable PCB, so no soldering is required for switches. The KEEBD Reviung 5 requires soldering diodes and a controller, making it more suited for those with some electronics experience.
The product listing mentions RGB and lists WS2812B LEDs as an optional item to purchase separately. The base kit does not include these LEDs, so RGB lighting is not a default feature.
According to the vendor, the gasket mount design with a PC plate aims to provide a soft and bouncy typing feel. User reviews mention it sounds 'thick' and has good sound dampening from the included foam, even without additional mods.
Yes, both are programmable. The Feker JJK21 uses proprietary Windows software for programming. The KEEBD Reviung 5 uses open-source QMK or VIA firmware, with precompiled files available via a link in the product description.
The Feker JJK21 kit is more comprehensive. It includes stabilizers, a USB-C cable, a 2.4GHz wireless dongle, EVA foam, and a battery. The KEEBD Reviung 5 kit is spartan, containing primarily the acrylic plates, PCB, and hardware like standoffs and screws.
A user review confirms the JJK21 has an automatic sleep mode in its Bluetooth and 2.4GHz wireless modes, which can cause the first keystroke after waking to not register. This issue is not present when the device is used in wired mode.
The Feker JJK21 is a 21-key numpad with a knob, designed as a companion for data entry and media control. The KEEBD Reviung 5 is a 4-5 key macro pad, designed for triggering specific shortcuts or commands, not for traditional typing or number entry.
No, neither the Feker JJK21 nor the KEEBD Reviung 5 include keycaps in their base kits. You must purchase keycaps separately to complete either build.
