Bought the cheapest and what I think is the best for people who knows that they want and what they are doing with it. ha ha ha
As mentioned by others and myself, not really recommend to buy 1 GB RAM boxes. However if you know what you are doing, and knows its limitations - it is a cheap and safe bet.
Just also found out that the 1GB DDR3 Tx3 comes with 16GB high speed eMMC ROM. Always when I see 1GB, the next number is 8 GB. But not this one. Probably my reading too fast. Now I see properly, it is 16 GB eMMC ROM. The more the better, can store a lot of Drama mp4 files. Should have about 11GB ROM left to download and store lots of apks and mp4s
The 16 GB high speed ROM, Also helps in cases where some apps doesn't work well if its data files are stored in External micro SD card.
Albeit, 1GB boxes not recommended to install a lot of apps. Limit it down to less than 10 if possible. More so if apps are not from Google AppStore, and does not have RAM usage optimization. Don't complain, lag this, lag that, streaming video lag, crash this crash that, :-P
Bought this,
[Click Here RM88 ONLY], as a community service and to see how far I can push the box and its limitations. Again, if first time buying box - really sincerely from deep down, get the 2GB RAM boxes. That is the bare absolute minimum to get a good experience playing with these Android Boxes. It is like paying for a Perodua and expect it to perform like a Mercedes, then go back complain and give bad rating to Perodua salesman

. If you want Ferrari experience instead, then Nvidia Shield is the best of the best.
Note:- According to experts, disabling Google Play services in 1GB box will give it the nitro booster power hahaha. Just kidding. As long as you know what you are doing and understands the 1GB box limitations, by all means go ahead.
