A bad purchase.
Once ordered, it took about 25 days to arrive. When i received the keyboard, it was too small to use for anything. When I tried to use, It wouldn't work. The keys were working fine but touch pad was giving bad response. I filed for return, and the very next day, a person visited to collect back the product. After that i waited. Waited for 25 days for anything to happen but no status change on order. I filed a compalint with amazon but no response or acknowledgement email from them. It's been more than 1.5 months now and the order is still reflecting as pending return. This was by far the most troublesome experience i had with amazon and bad first purchase from Rii

The keyboards are too close and therefore you always have to look at the keyboard to avoid making mistake but most of the times you hit two keys at the same time. the track pad is even worse. it doesn't create a smooth movement when scrolling, is not sensitive enough and is not pleasant to use.

Es un producto de alta calidad; con un precio muy razonable, está padrisimo. El único detalle es que las teclas eran demasiado pequeñas para mis dedos.

Had this keyboard for a couple years now, and its honestly amazing. Build quality it amazing, battery life amazing, usb-c, touchpad works great, and the bluetooth range is really good 30 plus ft. Only thing I could knock it on is size but that can be a good or bad thing. It is compact, but is too small to have your fingers on home row. Overall fantastic product.

Great job, Rii! This is exactly what I was looking for. I use the keyboard as a remote way to control a Windows 10 Acer laptop, which is connected to my Vizio 42 in HD TV, in a large living room (approx 30 by 20 ft). The dongle is sleek and non-obtrusive. Popped it in a USB 2.0 in the back of the laptop. Self install was about 5 min or so. The keyboard itself is sleek and compact. Exactly what I wanted to control my laptop and use as an entertainment center from the couch. I can't type very well on it. It's a little small for my fingers. But since I only use for searching Netflix, it's exactly what I want. I wouldn't be able type for work on it. The battery is amazing. It said not to overcharge. So I just charged it for 30 min until the light was not blinking. I've had it for weeks, and have not charged it since. I'd say I give it light to moderate use, but only to turn on music or Netflix, and then it can go to sleep most of the time. It goes to sleep by itself after a few minutes, and pressing any key wakes it up. It has this nice blue light on the top that flashes as it wakes up, so you know it's happening. Takes maybe 3 seconds to wake up. The mouse trackpad was a must, and this fulfills the purpose. It's hard sleek plastic, so my thumb slides right over it while holding the keyboard 2 handed. For mouse movement, it is flawless. Windows ten has nice big icons, so I use the mouse the most anyway. One and 2 finger sensation work well for tapping. It has dedicated right and left click keys on the bottom left of the keyboard- a little weird, but I never use. 2 finger scrolling is not only way too sensitive, but unreliable. Cursor key scrolling is smooth. The dedicated function buttons are nice- and they default usable functions, not F keys- thank goodness. Sound up/down/mute, default browser home page are some of the most useful. Also there is a OS button(?) that functions as thought you had the Windows key on a PC or like the clover key from apple, so you can toggle back to desktop - that's the only shortcut I use it for - I'm sure there are others. Pro: Sleek and nice feel, super thin and light. Feels like it won't break. Battery life/power save - I mean I haven't charged it since I got it. around 3 weeks. It sleeps. It wakes up easy No problems with range anywhere in my large living room-kitchen. I get maybe 10 yd away at most. It works fine from farther away than I can read the 42 in screen. Con: The M key is sticky. Random. Typing is a challenge d/t how small the keyboard is 2 finger scroll is unreliable
