Ten-80 out of business

I'm assuming they closed their doors as I finally tried to look them up and call the phone number (disconnected)?
I've wondered for about a year and 1/2 now what happened. I've searched and cannot find any information on them.
Amazon is still selling a few of their items and again assuming they are liquidating current remaining inventory.

I really like their products and bought quite a bit from them over the years.

Anybody know the story or inside scoop?

I also like amazons product.
