I got the Model 3 (single driver) about two years ago. Good overall build quality and the sound is great for the price.
Backed 2 pairs of their first TWS model and those were a little dissapointing. Charging did not work for the left pod from the start and i ended up returning them. Year later the second pair developed same issue.
Nismo Jr. I use for teams meetings on the road but they are very uncomfortable and i can't get a good seal with any tip size.
I also have the TWS ciem's and been very happy with those. Actually i haven't seen any other tws ciem's on the market.
That's my experience with ADV products so far.
