Mini Wireless Keyboard 2.4G XBMC Keyboard Touch pad Mouse Combo Multi-media Portable Handheld Remote, Rechargeable for Android/Laptop/Smart TV/PC Stick/HTPC/IPTV/Raspberry PI/PS3 PS4 KODI WINDOWS MAC

Bought this for a Raspberry Pi 4B. Wanted something small and wireless to avoid more clutter and cables on my desk. Initially it worked fine, but then stopped working. Tried charging - no luck. The manual does not explain the status lights but I'm pretty sure I'd connected it okay. After 30mins charging still would not respond. I even changed the rechargeable battery (Nokia BL-5C). This kept the charge light on so left it for 90mins. Still no response. A pity because when it was working it was a very good product. Will return it to Amazon.
