That is what I figured out. There are a bunch of models. The MX, MK Maxicom, Maxicheck, and I think another one. They are all the same. Just sold by different parts of the company. “Kind of” like Pontiac, Oldsmobile, Chevrolet.
The MP Maxipro seems to have more software for imports. (Audi, VW, BMW)
The suffixes make a bit more of a difference. 808s and 808z seem to be the same. Base model with a cable. But does not do battery tests with the optional adapter. 808bt and 808s-bt (same but uses BT adapter and shows it can use the optional battery tester.
The 808s-ts or the 808z-ts looks like the same model too. But they can use the optional battery tester and they do TPMS service.
Hope this helps some. If you look at Amazon you see these models and the say MX same as MK. No guarantees on how accurate I am. But I think this is close.
Then the 900 series has internet diagnostics. So that is another world over the 800 series.
