Rii i25 vs Rikomagic RKM MK 705 wireless air mouse

The Rii i25 and RKM MK705 are both wireless air mouse with IR learning functions and a mini QWERTY keyboard on the back.

If you look at the specs and design, they look exactly the same

Rii i25


My guess would be that both are manufactured by the same OEM company and simply re-branded accordingly.

Rii however has another model which is the i25A and this model includes a microphone which you can use for voice control and voice chat. So if you do not need a microphone, either Rii i25 or RKM MK705 will do. Just choose one that is cheaper.

Physical Aspects

The controller is slim and considerably light and that makes it nice when hold. This is the main reason why I chose this over MeLe F10 which is too thick for my liking.

On the main side are all the basic buttons to control your devices like the page up/down, volume, and music/video playback control buttons.

All orange buttons on the controller can be IR 'learned' and the process is very easy. This allows you to replace your TV remote controller by making it learn basic common functions like power on/off, source and volume up/down.

On the left side is the on/off toggle and also a micro USB charging port, so do remember to turn it on before use else you might think that it is malfunctioning like I did!

Left side

The built-in battery do last quite a while before it needs recharging and it can be charged with any USB powered source.

The keyboard on the other side is handy when browsing or chatting and way easier to use as compared to the Android on screen keyboard.

Mini QWERTY keyboard
The only problem is that the transceiver is located at the top of the controller therefore when used as a keyboard, depending on how you hold it, your left hand may block the transceiver and this can cause some inaccurate commands to be sent.

The buttons tactile feel is OK for me though may be a little too hard for some people.

Overall I am satisfied with the controller though the transceiver location issue do bug me at times but I guess it applies to any air mouse.


Slim and light; nice to hold

Up/down button needs to be IR 'learned' for use with Android devices.
Transceiver don't work well when used as keyboard due to design

Tecno TSH5030R Electric Water Heater

This is the smallest capacity model from Tecno's range of horizontal storage water heater even though the manual states that there is an even smaller capacity model (25 L) as well as various other capacities. Tecno however only sells the 30 L, 50 L and 90 L models.

Although I posted about how a vertical storage heater is better than a horizontal one, this being almost similar in vertical and horizontal dimensions (540 cm x 380 cm) will not make much of a difference

It comes complete with all the necessary accessories including the installation brackets and mounting screws. The tank can be mounted on the left or right and on the floor or ceiling therefore placement shouldn't be a problem.

According to the manual, it is energy saving as the temperature of the heated water will be maintained up to 2 days after the heater is powered off.

I recently purchased the heater from Lazada for $178 nett after using a promo code that knocks some bucks off the actual price together with their free delivery promo on their app.

Warranty is only for 1 year for heating element but 5 years for the tank itself.


 The box it came with

The box includes all the necessary accessories to have it installed, including brackets, wall mounting screws etc.

The technical ratings on the control panel which is configured for right side mount. If you plan to mount on the left side, you have to rotate the control panel face plate.

The simple control panel consists of a dial for temperature settings and light indicators for heating and power.

After installation (before cleanup)


If you plan to perform a DIY installation, then the following are some tips

1. Get a 16mm drill to mount the wall mounting hooks
2. You will need a torx screwdriver if you need to rotate the control panel
3. A ratchet set will help to screw the mounting bracket to the heater
4. You may need the help of someone else to mount the heater to the wall hooks but I was able to do it on my own as it was not that heavy. Just be careful
