Wireless Mini Keyboard with US Layout and Touchpad Manufacturer: Made in China, No-brand product Wireless Frequency: 2.4GHz Keyboard Layout: US layout Additional Features: Touchpad included Included: Dedicated USB receiver, 1 manual, 2 used AAA alkaline batteries (replacement recommended) Shipping Method: Scheduled to be via Nekopos (Supplementary Information) Purchased new and unused on Mercari in September 2024. Used for about a month as a remote control for watching videos on a living room PC, but has been stored since then. Shows little signs of use and is very clean. The batteries were new when purchased and haven't been replaced since, but are still working. Battery life seems to be quite long, possibly due to the auto-sleep function. Communication is also stable. Overall, the build quality is quite good for a no-brand product. The manual was lacking in detail, so I've added some supplementary information based on my experience (see image 7).
