Works great. Keys have decent feel, includes both the keyboard and a track pad, and is wireless via USB. The USB receiver tucks in the battery compartment when not in use. It is small, as seen in the photo next to my full-size Logitech MX Keys keyboard. Fits in my backpack when I need a better keyboard than the ones in my office. Also, it works great with my Raspberry Pi.

My rating is strictly for the product. However I did buy this because I needed a bluetooth keyboard and this was listed a bluetooth keyboard. The keyboard serves its purpose. Its a general use keyboard for designed to give you mobility. Its practical, no bells and whistles. Im giving it 4 stars because: 1 - doesnt come with a manual (which you dont need if you are just connecting to computer), however its a bit complicated if you want to connect to a TV. 2 - As far as connecting to TV, The only piece of paper I got was ikea style instructions on connecting to a TV. Which doesnt appear to be a true connection.. its seems like you are just connecting your laptop to the tv.. and the keyboard connects to the laptop.. From this point of view, it does not seem like you can connect to your smart TV and type into whatever app you are using. The setup is basically connecting your laptop to a TV. 3 - Price point: at this price, in 2024, I think is adequate considering brand name, and practicality. There are probably other brands at same price point, maybe lower, that probably have bluetooth but Im a consumer that likes to use brands im familiar with. I do try other brands but this was an immediate need purchase, theres nothing wrong with the product, it just did not provide the features the website said it did. Im not returning it because im sure i can find use for it, in the immediate future. But I just feel the waste of my time and missed opportunity of making money ( I had bought it for an $800 gig job - which required a bluetooth keyboard as part of the equipment) is more painful than the price. I trust bestbuy and I trust logitech so it was one of those situations where i didnt really read specs and do price comparison.

Great wireless keyboard and touchpad. USB receiver means no hassle pairing with Bluetooth. Perfect if you have more than one computer or device with USB, you just plug the compact receiver into the USB port and away you go. Uses AA batteries so no frequent recharging, batteries can last well over a year depending on use. There's even a great little storage space inside battery compartment to keep small USB receiver when not in use or traveling. Great keyboard at a great price.
