Due to stock issues on certain certified models, have limited options coming and going quickly.
As of Nov/2025 the Mecool KM2 Deluxe is the only Google and Netflix Certified 4G AndroidTV model available on the market and that I stock.
Have some more X96Q arriving Nov.10th as well as the Hako Pro 2G ( 20 pcs only of hako)
Hako Pro Mini is a 2G ATV fully certified,  found last 20 pieces avail and are on way for pre-order.
I have a line on a few non Certified options still using AndroidTV OS , cheaper models that I will regularly stock if performance meets expectations. 
Will have some new options posted in coming days or so in regards to the AndroidTV operating system,  which is still the best for streamers.
If Netflix or Google certification isnt an issue for you and you dont use subscription services,  the X96Q or HK1 will be more then good and are 4G.
