Moxie rings for beads

Moxie must be an after-market brand, but seems often to be offered by TB dealers.
This is a completed listing on ebay for a Moxie ring, 'Princess' style:

Anyone have any experience with these?
I've seen them IRL at one shop, played with it a bit. You hold the ring upside down, place a bead over the prong, slip your finger in (with your palm up). Then when you flip your hand over to a normal position, the bead is held between your finger and the V-shaped swirl of silver. Is it really secure? Comfortable?

(BTW, retail price is about a hundred bucks, that ebay buyer got a deal.)

yes i love them. they retail for at least $125.00 plus tax from jewelry stores and other stores that carry them. i have two of them. the original style and the princess style. i wear my troll coin in the princess style ring and my rolling waves people's choice bead in the original style. it is very comfortable and secure. i also love One Jewels rings to wear my trollbeads in. I love all of these after market accessories for trollbeads. Marcus Max is another aftermarket jewelry line for Trollbeads. All other brands will fit also.

my LD carries these-

I've tried them on, but never bought one

I'm impressed Bubba, that the coin fits in it- THAT would be cool!!!

The lady that made them is one of my local TB dealers. They look like fun, but I don't have one... I'd rather spend the money on the beads I guess!

Does anybody have a pic of the ring worn ? I just can´t imagine the dimensions.
