Customer ratings and reviews for HP K4000 Bluetooth Keyboard

Rated 5 out of 5 by Works across multiple devices Only had the HP K4000 Bluetooth Keyboard for a short time but tested it immediately with MotoX (Android phone), Nexus 7 (original 2012 model) and iPhone 4 (work phone) and it connected to each with ease. Excellent keyboard layout. The keyboard works well for me but might be awkward for individuals with larger hands. One suggestion for HP is to include a keypad map at least online. Not sure what all the fn key options are, e.g., what is the F12 fn key suppose to be? July 20, 2014
Rated 4 out of 5 by Greatness I enjoy using this keyboard very much. The design is quite excellent. It compliments my ENVY 23" monitor and soon to buy X7500 mouse. It works well in Elementary OS, Archlinux, and Windows 8.1 I wish it had a tiny little dot on the cap locks button lit up whenever you hit the cap locks button. July 9, 2014
Rated 4 out of 5 by Great keyboard for a tablet I use this keyboard with my Omni 10 Tablet and love it. The keyboard is the perfect size to carry with the tablet and I really like the flat keys. The connection problems mentioned in other reviews may be limitations of the Windows 8 environment. I've had connection problems with other bluetooth devices and Windows 8, but for the most part the problems have been minimal with this keyboard compared to other devices, so I won't blame the keyboard itself for these small issues.

Rated 2 out of 5 by Poor Performance The keyboard worked well for the first hour and then had to be re-paired with the computer. Seems it can't remember where it should work. Thinking that the battery may be the problem I replaced it only to have to repeat the whole pairing process again and again. The range of the keyboard seems to be a factor as well since you can't operate it if you are more than about 2" from the computer. May 29, 2014
Rated 2 out of 5 by Below my expectations The hp 4000 Bluetooth keyboard did not work for me. It seems cheaply built and did not perform to my satisfaction. I could not keep the Bluetooth connection established. It would lose the connection several times in a short period of time. I would reconnect the Bluetooth connection and it would drop again. After doing this several times. I put it back in the box and it is setting the shelf. If you want a wireless keyboard, get one with usb not Bluetooth. February 6, 2014
