All of our tv boxes have the same Kodi programming on them and all work in the same way.
The price difference comes from the internal makeup of the box.
Our least expensive has no external antenna, an S905X processor, and 1GB RAM/8GB ROM.
As you go up in price, you get more features, like an external antenna, faster S912 processor, more RAM/more ROM and dual-band wifi switching. For watching tv shows and movies, the higher priced boxes perform exactly the same as the lower priced.
We offer different choices because some people are looking for an inexpensive option and some people want more RAM/ROM, some want lots of games and some people like a lot of features.
We support our boxes for their lifetime, therefore we only sell good quality tv boxes.
