Package Content & Design
Rii i25 by Riitek comes in a simple yet well protected packaging. There are Y cable with micro USB plug, USB type A plug & jack, nano USB receiver, user manual and thank you card with support information there too. Rii i25 build quality is decent with solid plastic housing. All the buttons and keyboard keys are rubber except the D-pad which is hard plastic. Basically, the normal TV remote keys are located on the front. You can control Android TV box or use infrared key for TV. By the way, there are several LED light indicators on top that light up when charging and key pressed. And flip over for keyboard.
If you notice, there is a mini hole below the i25 Rii mini wording. Yup, it has no function on i25 but as microphone on i25A (or K25A) model which has audio input and output through earphone jack.
And the power switch and charging port are located at bottom left. As usual, do refer to all the pictures to understand more.

Performance Result
There are several revisions of Rii i25. So you might see some changes on the button layout. Mine is the latest version (with user manual v1.9). There might be some enhancements or bugs fixed too. But the major that you can see is the IR buttons changes. Mine comes with power, source, left, right and OK button. IR programming based on your existing TV remote is very simple. Just align them together. Long press i25 button for 3 seconds. Then press TV remote button will do. LED light will blink when successful. That’s it. And the IR range is good. Easily cover my whole living room.
2.4GHz wireless connection is great too. Passes 10m with walls and obstacles with ease here. Working perfectly on my Android TV boxes like RKM MK22 Plus. And Windows HTPC like MINIX NEO Z83-4 too. Basically, you just need to plug in the USB receiver and Rii i25 is ready to be used. One thing to take note. It will start with air mouse mode when power on every time. It might annoy certain people (like me) as I will turn on air mouse when needed on Android TV box (but great for Windows PC as mouse it always needed there). How to solve it? Simple, just lock the air mouse and leave the power switch turned on all the time. It will stay locked when you plug USB receiver to other devices too. No more mouse pointer here and there now. And no worry about battery life too. It will auto sleep when no key is pressed after 3 minutes. I still haven’t use up the first charge yet after weeks of casual usage. And self-charging is fast too.
All the functions are working properly and buttons’ feedback is good on Rii i25 as a standard remote. Media playback buttons are very useful at Kodi. Air mouse is smooth and accurate too. Playing Fruit Ninja type of games are possible thanks to that. Keyboard for text input is working as it should too. And lot of Fn keys like mute, ctrl+alt+del combo key for you to use as well. By the way, mouse will be automatically locked (or disable) once you flip over the remote for keyboard. And back to mouse mode again when flip over again. Isn’t that great?

Conclusion

It will totally change the usage experience on TV Box, smart TV and HTPC. As usual, more information can be found at Riitek Website. Buy yours at Amazon.
