The compact profile of a 60% or even tenkeyless board is great, especially in transit. But there comes a time when a numpad is indispensable Read More

Great little numpad. I have no complaints besides the lack of instructions. After searching the web and messing around with it, I figured it out. I wish you could change the numpad with RGB to just solid colors or different modes, but instead of multicolored LED's it comes with solid colors at different rows. Not a huge deal, but wasn't what I expected.
Here are the functions I figured out: Functions
  • F2+F1 - Cycles through top light modes
  • F2+F3 - Cycles through bottom LED colors / modes
  • F2 + 8 - Increases Rate
  • F2 + 2 - Decreases Rate
  • F2 + "+" - Increases Intensity
  • F2 + "-" - Decreases Intensity
  • F1 (by itself) - Acts as the F5 key
  • F2 (by itself) - Does nothing, acts as a Fn key
  • F3 (by itself) - Acts as a backspace key

I needed a numpad after switching to TKL so I would have an enter key in easy reach and this one happened to be available and cheap. The build quality is okay, but when I switched out the keycaps, the + key would jam when pressed on the top-right of the key. I pushed in the keycap very hard to try to deform the stabilizer or key into place and now it works fine. There's nothing else on the market that can touch this numpad at its price.

I got the numpad with Gateron Greens to use with my Whitefox which at the time also had greens.
It does what it's supposed to as a standalone numpad especially including that it sends true numpad codes which I feel is absolutely necessary for standalone numpads. The leds on the thing are a fun little addition, but also not something I care about. When it arrived, the plate mounted cherry stabilizers were not all fully clipped in, so that had to be fixed real quick. Some other negative points for it are that it doesn't save what underglow setting it was set to when it is unplugged which is annoying and inconvenient at best, and honestly the case design of it just doesn't fit in with any of my other boards. It's kind of petty of me to make a point of that, but it's true.
Nothing wrong with it functionally, otherwise.

This is the triumph numpad kit from the /dev/tty MT3 set from right here on Massdrop.

I've had it as a permanent feature next to my keyboard for nearly a year now and I LOVE it. It works perfectly and it's attractive. My only criticism (and it might be an issue with my PC and not the keypad itself) is that after I've been inactive overnight, I have to 'initialize' it by hitting the 'num Lock' button. But that's easy enough and not much of an inconvenience since it only happens when I first log in in the morning.

Rattles a lot. Enter key is very mushy

Not reprogrammable. LED's are dim and not adjustable for color. No internal memory for remembering color setting for under light. Keys rattle. Top keys are useless except for lighting adjustment. If all you need is literally a numpad and do not care much about whether the quality is top-tier, this is the product for you as it is a very cheap option.

Decent enough,
This is nothing fancy, and imo it’s probably a bit overpriced for what it is, but it’s hard to find a cheap mechanical number pad, so this may be the best option out there. I wish there was a tab, ctrl, and/or shift keys in the top row, but backspace and f5 for refresh are nice cheap stabs and keycaps, but oh well, not too noticeable to me. the whole thing is a cheap number pad, but considering I wasn’t willing to spend $90+ on one, I’m happy with my purchase I believe there’s a v2 on here as well? So if you’re reading this, check out the v2

It works.
  1. It works
  2. Honestly it's a fun little thing to mod
Honestly it does it's job and looks great next to the Anne Pro 60% Cons
  1. Plastic feels very cheap
  2. Stabalizers rattle a lot
  3. The mounting plate makes a tingy sound when the keys bottom out. My biggest gripe to be honest
  4. The LEDS are very uneven in brightness and one of them did not even work when the pad arrived
  5. I got the Gateron Browns and they were SUPER scratchy and overall unpleasant
I can't really complain all that much since at the end of the day it does work. I put in a different keycap set, fixed the stabilizers and put in Cherry MX Silvers Switches. I like it a lot more now but only after I put some work into it. I would also recommend not putting this in direct sunlight for long amounts of time. The white plastic case is very cheap and started to yellow as my desk is next to my window. Overall, dont buy this if you are into aesthetics or build quality. Buy it if you are looking for a neat numpad that works.

Leaving a review after modding! I love the design, plastic and acrylic aren't too bad. I thought the quality of the default black keycaps were great, but since this pad doesn't quite boast the amount of light I see/saw in the initial listing, I took it apart and removed the key LEDs. Switches:
  • Replaced the switches I chose for this, the Gateron Clears (first time trying them, felt too watery or loose), so I replaced switches for keys 1-9 with the Massdrop Halo Clears; the math keys, Del key, and the top function keys with the Massdrop Halo Trues (
  • The Enter and Num Lock (kept the default black keys on them) with Kailh Box Jades.
  • The whole intention for different switches was to get the feeling right for my buddy who just got promoted as a senior accountant. Felt he needed something to make work feel good again. Haha.

  • Colored keys are the Backlit Doubleshot Gradients (
  • Black on whites EnjoyPBT
  • Default black keycaps that came with the pad

  • Lubed just like Taeha told me to :)
Very fun project, great item to mod!

I feel as though the overall design of this number pad is very half baked. If you need a number pad just for the actual number pad functionality and neat aesthetics, then this product is for you. If you want an extra set of keys for macros, functional F keys, high quality mechanical keys, and lights that actually save settings when you turn your computer off then you will want to look elsewhere.
