In this video I tested the 70mai T800E and focused on what makes it stand out right away: it’s one of the thinnest 3-channel dash cam setups I’ve used. If you want true “nothing gets missed” coverage, a 3-channel system is the move because you’re getting front + rear + cabin coverage, which is basically the closest thing to 360-degree protection without doing anything complicated. I walk through what the setup looks like in a real car, how clean the install can be with a slim main unit, and who this style of dash cam actually makes sense for. I also break down what matters most in day-to-day use—how the footage looks in normal daylight, at night, and in rough weather or low-light situations. The whole point of this review is to answer the question: is the T800E actually worth buying if you’re shopping for the best 3-channel dash cam for full coverage? My takeaway is simple: if you want a compact, clean-looking multi-camera system that’s built around capturing everything happening in front, behind, and inside the car, the T800E is a strong option to put on your shortlist.
