I have a set of triple square bits. They are held in loosely in the smaller sizes, with set collars in the larger. I used them for quite a while before I went to VIM. Probably well within the quality margin for home use.
Some of their stuff is stupid overpriced, others quite fair, at least via amazon pricing. If I had to guess, they're a Taiwanese importer who buys from the same people who feed ampro, OEM, neiko, etc. Long offset box wrenches have the same design credited to "infar", suspected supplied to channellock and carlyle, for their funky open ends. FWIW, I have a set of the carlyles with that gnarly open end, they're simply "okay".
They once sold semi-deep 1/2 drive impact sockets, the only seller outside snap on I've seen to do so. They became discontinued before I purchased a set and I regret it to this day.
As for the triple squares; I still have them, they still work fine. VIM is a much superior product, but I got the genius from a member on here IIRC. VIM is also more expensive, YMMV.
