Wireless Numeric Keypad, 2.4GHz Portable Number Pad with USB Receiver, 22-Key Number Pad, for Laptop/Notebook, Desktop/PC Computer Compatible with Windows and OS X System(Black)

I bought this wireless numpad as my keyboard does not have a numpad built into it. Very easy installation, just insert 2xAAA batteries into the rear, as well as removing the USB dongle (where the arrow is) and then inserting into a PC. In terms of using it the numpad has good feeling switches, and is very responsive despite being wireless. The calculator shortcut is a nice feature. Overall, nothing to complain about for the price. Are there better feeling numpads? Probably if you pay more, but for the price it lets you use a lightweight numpad with no external wires, and is plug and play (just don't lose the dongle as it is very small). What I was using: Desktop PC with Windows 11 installed, I thought this was necessary to say as I cannot say personally if it works with MacOS or Linux.

My Macbook has a limited keyboard size, so this is great for accounting / using with my music transcription software. 2 x AAA batteries and a simple set of instructions to follow. Worked right out of the box!

Good little device. Clear numbers and easy to set up on my Macbook. However I can't get the calculator to appear on screen ... maybe I'm missing something.

I bought this as a replacement for a Microsoft number pad bought here on Amazon that in itself was a replacement for another Microsoft numpad that had given up the ghost. I initially bought the MS one as it was supposed to work any and everywhere. Nothing could be further from the truth. I received the MS one and tried to get it to work on my Linux distro without success. But as I have a dual-boot system with Win10 installed as well, i tried the MS product on that. It worked at first but after a reboot it wouldn't connect to Windows. So I returned it. Now I bought this number pad to replace the 2 MS ones that failed me. I put the receiver into a spare port, on a hub I might add, and it just worked in both in Linux and Windows without any issues whatsoever. And to cap it all it was about a third of the price of the Microsoft one. Go figure. It's just a straightforward no-nonsense numpad and works right out of the box. What more can you ask for?!

Was genuinely surprised what good quality this is for the price. Worked straight away out the box and no lag in performance from button press to response on screen. Great space saver for my home desk as meant I could get a smaller, more compact key board as well.

I have used this now for 6 months and for the price its ok, but not great depending on what you are doing. I bought it because I got a 3/4 keyboard which is better for you when using a mouse a lot, and I also occasionally need one for my laptop. I only occasionally need to do a lot of data entry - this is when this item falls down as the keys are not as responsive as you need it to be, when using it at speed it doesn't capture all the numbers as you would need, so errors creep in.

Pretty dangerous in my opinion. I only had it switched on when I was actually using it, and even then it caused the batteries to corrode so badly that they started leaking. Battery acid/alkaline leakage can be harmful, so I'm keeping an eye out for any skin reactions after handling them. Definitely not what I'd expect from a product like this.

Had a computer keyboard at work without a number pad. This is a great addition, as I do a lot of work with numbers and couldn't cope without, but didn't want to purchase a whole new keyboard. Is great because it can sit in your desk drawer until you need it, so a smaller keyboard doesn't take up as much room.
