Phone number Crenova gave didn't work so tried second phone number. Got a person with a terrible connection. They did follow up with a prompt email, though, but it was the "We're sorry, please provide photos, videos, more info, etc." and I didn't have time for that mess, so I contacted Amazon and arranged a return. I am satisfied that this unit, which I think was shipped by Crenova, was a return, because the box had been opened, the remote had batteries already in it, and the unit did not work.
So, since it seemed to be bright enough, I ordered one of their BL-76 models (red) that is shipped by Amazon and will arrive in 2 days, hopefully with none of that previously returned unit nonsense. I'm ordering this one primarily because it will arrive quickly, and a direct replacement would require another week, but there are advantages to this one, like it has manual buttons instead of the insanely bright yet hard to read touch panel. In any event, it's how I had to go, and I will update here when I get it.
