I purchased this for use with my new Dell 16 2-in-1. No dongle was a must for me. I’m tired of dongles using up USB ports. That being said, the BT was easy, fast and painless as it paired to my Dell. It couldn’t be any easier. Absolutely no issue connecting immediately.
As a long time professional pianist/keyboardist (and typist), I’m very picky about the feel of the keys. The key travel distance. How it feels when you hit the bottom. Is the touch too light? After testing it out thoroughly and using it a lot, it is exactly what I wanted. The keys are solid and have enough resistance so that you don’t continually “tweak” a wrong key next to the one that you want.
It has all the functions you could want on a numeric keypad. Every option works perfectly.
I gave it the initial full charge. I’ve been using it for countless hours. OK. Weeks by this time. Still haven’t needed to recharge it. I leave it powered on 24/7. The sleep function works nicely. In fact, I was surprised to find a nice function as I would cold boot the Dell. I use the 4 digit code on the lock screen. I type the digits on the keypad while it’s still asleep. It wakes and remembers the digits I typed to unlock the computer. Pretty awesome.
The unit is well built. Feels solid to hold in your hand. When it’s set on a surface next to the computer, the rubber feet keep it solid and steady. No sliding around while typing. I couldn’t be happier. The price is great. I’ve recommended it to many friends and family. They have purchased it and are as happy as I am. Unless you get a “lemon” (it happens), this is more than worth the money. I highly recommend it. I’m sure you won’t be disappointed. BTW . . . I just discovered that it’s on sale. Time to get one.

The layout and size is great. Not to large, nor too small. The only reason to doc it one star is because the battery life isn’t as expected. Also once the battery starts going down there can be miscommunication with the Bluetooth connectivity resulting in missed or doubled entered numbers. After realizing it was a battery problem plugged the cord in and good to go. It also works while the cord is plugged in thus would like to give a 4.5. Not sure how the battery will do while plugged in often but y just leave it plugged in most of the time. Review is roughly 2 weeks after purchase with minimal usage most days and 2-3 hours on a couple days.

Plug n play. Works as expected.

I’ve paired this device with an older (5 years old +/-) HP Pavilion laptop with little difficulty. It arrived on time in modest packaging that included a charging cord and an “instruction booklet.” (Why do mfrs call a small sheet of paper folded in half a “booklet”?) The device has good weight suggesting it is solidly built (and likely due to the rechargeable battery too). The key function is smooth with zero delay between key depression and numbers appearing on an Excel spreadsheet. Pairing the device to the laptop was slightly twitchy as the laptop seemed unable to immediately discover it. A few clicks in the laptop settings and I learned it was user-related. I’m not a fast 10-key user – I purchased this for spreadsheet entry of historical census data and get annoyed with repeating the cycle of moving my hand from the mouse to the keyboard and back again. I’ve positioned this adjacent to my mousepad reducing the hand motion to a minimum (crazy world we live in when moving your hand a few inches repeatedly is an inconvenience – oh well…). The key pad has all the function keys I’ll ever use, and more: backspace, tab, num-lock, escape, delete, insert, etc. For the finance-related users there are keys for dollar, Euro, and Yen. I’ve used this exactly one time for about 2 1/2 hours with no difficulties or experiencing any issues that would cause me not to recommend purchase.
