Rii K18 Plus Wireless 3-LED Color Backlit Multimedia Keyboard with Multi-Touch Big Size Trackpad,Rechargable Keyboard for Android TV Box,PC,Smart TV,Xbox,Raspberry Pi, HTPC IPTV,Windows, MacOS

Edit: I've had this thing for about a year and my opinions have not changed. It's a solid mini-keyboard and definitely worth the price, holding up well. Charge lasts 4-6 weeks before having to plug it in. Touchpad has sort of lost its texture from all the use, but still works well enough. Keys are small enough that they're difficult to type on, but finger peckers / typing novices will find it just fine. Charge indicator has never worked, nor has the low battery indicator. It has always just lit up the wireless LED when charger is plugged in. So the only warning it's going to need a charge is when it simply stops working. Not a deal breaker, but hope they fix that in future versions.ORIGINAL REVIEW:I've owned this keyboard for about 6 weeks now and it's an absolute gem for a home theater PC. It's proven durable so far, having four kids tends to put handheld devices through quite a torture test. The backlight LEDs are bright and having the three color options is awesome.I've used plenty of expensive brand name keyboards, and the touchpad on this is among the best. I don't like that there's not physical mouse buttons under the touchpad, but thankfully there is a physical left click button (on the left side of the keyboard) that saves the day. Perfectly usable is how I'd describe it.The keys are small and hard to type on, but nothing worse than what I've experienced on any other small form factor HTPC keyboard. They work just fine otherwise.I really love that the F1-F12 keys are the primary button, and you have to hold down the FN to access the secondary media functions. A lot of HTPC keyboards have this backward where you have to hold FN to use F1-F12 keys at the top, and media keys are the default-- I'm a PC user going back a couple decades, so not having native F1-F12 keys is almost impossible to get used to. This keyboard does it right in my opinion.I'm 6 weeks into it and I haven't had to charge it other than when I first got it. My kids and wife are the primary users and they know to switch the keyboard off (it has a power switch on top) when they're done with it. Switching the power on activates it immediately, I've never had to reconnect the transmitter or do any kind of re-pairing. If you leave it set for awhile with power on, the backlight turns off and seems to go to sleep on its own, but wakes right away with any keypress or mouse movement. It just works every time.The only flaw I've noticed is that when I plug it in to charge, the wireless LED turns on. I can see that there is a low battery indicator, and a battery charge indicator, but I haven't seen the charge LED light up, even with the charger connected. If you have the keyboard switched off or on and plug it into a charger, the wireless LED lights up. I've verified the keyboard is taking a charge by connecting a USB load meter to it in between the keyboard and charger. It draws about 300 milliamps anytime the charger is connected, which tells me it's charging just fine. That said, I've never depleted the battery, so I'm not really sure if the low battery indicator works. But the charging LED certainly doesn't, it turns the wireless LED on instead while charging. Why? I'll never know but since it seems to be charging fine, I won't complain. I'll know for sure when it finally runs dead whether the low battery indicator works, and will try to update this review.In conclusion this is an awesome keyboard and works perfectly for this application. My last keyboard was an expensive Logitech and the charger port broke off a few months in. This keyboard works better and using the touchpad is a much better experience. This has a USB tether for charging (that slips inside a plastic cover) which will likely last a long time if not abused. They also include a USB extension cable in the box so you don't have to put any strain on the short USB tether. The fact there's no charger port to break off is a good thing in my opinion. I really feel like buying a couple more of these just to store away in a closet because I'm sure it won't last forever and they will probably stop making these at some point-- this keyboard is that good that a spare or two would be nice to have and the price is right!

Logitech no longer makes the K830 so I bought this as a replacement since my K830's micro usb charging port is broken. This is the closest you will get to a k830 replacement since the other Logitech multimedia wireless keyboards do not come with backlit keys.Things I like:(1) Better backlit keys than the k830. The k830 does not have a backlight for the FN keys and some secondary key icons. All the key icons on the RT518S lights up.(2) No micro usb charging port. Micro usb charging ports are notorious for breaking over time. This has a built in USB A charging cable.(3) Super compact and lightweight.Things I don't like:(1) Build quality noticeably lacking compared to k830(2) No physical trackpad buttons. If you like physical left and right trackpad buttons then this is not for you(3) Built in charging cable is short. They give you an extension cable, but it still feels too short with it.(4) Firmware updates require an Android device. Not sure why you can't just do it over PC and bluetooth.Despite me having more things I don't like about this device I feel it is still the best replacement for a k830, and would recommend other k830 users looking for a replacement with backlit keys to try this one out

I love thianlittle thing! I bought this as a replacement for a standard wireless keyboard and mouse that was not backlit, as I needed the lighted keyboard for the darkened man cave. That keyboard has a single sensor for both the keyboard and mouse, so I also needed to replace the mouse. I found thus delightful keyboard and pad and after some loking arpund came back to it and ordered it. I installed it today.It was a bit smaller than I had expected, but its a full sized keyboard. It size turns out to be just right. I pushed in the USB dongle to a slot on my PC and turned on the keyboard and it worked. Just like that. No drivers, no setttings, it just worked! The keys are not high cubes like a standard keyboard, its like they are just the tops. They set just fine and are very easy to the touch. The lighting is perfect, red, green or blue, easily changed from the keyboard. The touch pad is senstive and feels just like the one on my Macbook Air.This was a good purchase and I am pleazed with the quality, the price and thw functionality! Highly recommend.
