SOLAKAKA K21 RGB Backlit Tri-Mode Wireless Mechanical Number Pad Supports 3 BT/2.4GHz/Type C Wired,Hot Swappable 21 Keys Mechanical Numpad with Transparent Keycaps

For $30 I expected this to be a cheap plastic keyboard that would fall apart in a few months. I am happy to say that it is neither cheaply made nor has it fallen apart. In fact, I actually quite like this numpad. It connects via USB A and has several secondary functions that can be initiated by holding FN while pressing other keys as indicated by the keycaps it comes with (I recommend not changing the keycaps). It's small but not too small and is about the size of a numpad on a standard keyboard. The sides of the keycaps are smooth clear plastic while the tops are a bit textured and have some color. There are several RGB functions, but with my configuration the RGB lights up the keys and fades in a satisfying manner when each key is individually pressed. The switches used in the construction of this numpad also add to that satisfying feel, and I haven't seen a mechanical keyboard on Amazon with the same kind of switches. TLDR: USB A connection, cool RGB, extended functionality with FN key, very satisfying to use. Overall, I'd say that this is a good quality numpad that exceeds the value for its $30 price tag.

For its price it is very good quality. All keys are responsive and have had no performance issues with key ghosting. Using it wired. As far as the sound and feel I made some modifications which took it from very good to perfect: took it apart and added tape to the bottom of the pcb. Used a piece of the foam that came in the box to fill the empty space under the pcb. Replaced the switches and the keycaps. Note: the switches will affect the led color. Some of the switches I used have a red base and it makes the led look pink when I set it to white, as it shows on the photo.

I used this via Bluetooth via Win 11 only. It does go into a sleep/auto-off standby mode when not plugged into power and idle for sometime. However, it wakes and connects quickly. Feels very solid with good typing quality. This is next to a very high end keyboard and I'm impressed frankly. Totally recommend.

I like to have a separate 10-key pad so it's not in the way when I am gaming. This handy device let's me do that and provides a macro pad on the left side of the keyboard when I am playing MMOs. The build quality is good and it can be customized with different switches and keycaps if desired. My only complaint is that the base is kind of thick so the bottom row of keys is slightly higher than the main keyboard. If it were thinner, I could make a base to get it to match the main better.

The first strike of a switched (key) does not register, thereby forcing the user to type it twice, sometimes 3 times. For example, if I want to type 2001, I would have to type 22001, or 222001. I learned how to type in 7th grade in 1981, so I type without looking at the keyboard. My work requires high speed, no-looking-at-keyboard typing. I cannot afford to slow down and dart my eyes back and forth between the keypad and the screen in order double check on whether my numbers entry are missing the 1st digit, or contains duplicates of the 1st digit. Computer tech equipment is supposed to make the user's life easier, not harder. This numbers keypad is non-functional for its intended use. As such, it is a dealbreaker and I have to choice but to return it.

I got this because I needed a new numpad that could be wireless for ease of use between 2 PCs. I can switch it to bluetooth 3 for PC 1, and switch it to 2.4GHz dongle for PC 2. So far I've had it for a few weeks now and it's performed admirably, and looks pretty as well. I mounted it on an arm in order to keep my desk clear for gaming.

I used this as a streamdeck alternative and for repetitive number inputs. It looks great and feels like a natural extension of the keyboard. Only thing I don't like about it is that it's easy to hit a button combination that will make you feel like it's bricked. I have to look up the manual because I don't believe mine came with them.

I use this for work primarily, this is great, the keys have a nice rebound and the sound is creamy music to my ears. They transparent keycaps are a nice touch to allow the RGB to shine through, although it's not really a big deal for me. I will say that if you're using BT mode, you may have to tap the key twice because it seems to go asleep fairly quickly but that is not a big issue for me, just a buyer beware for those that hate inconvenience, it does also come with a dongle so there's that.
