Never heard of them before but I read the blurb on the ad and it sounds like you got a bargain. Watch your sleeves though if you change the tooling while its still revolving!I know vaguely what they do but I'm not entirely sure, could someone explain please?
Has anyone used one?
I ask because I just bought a couple (MT 1 & 2)on eBay as they were cheap.

That's what I thought, perhaps that's why they never became a common item!

They arrived today
.
I'll go out and try one later. I was expecting the internal tapers to match the external tapers on each chuck but they're both Morse No.1 inside
. They're pretty much useless on my mill with such little room between the table and spindle but they might be nice on a big pillar drill, I just couldn't say no for the price.

Tried them out, lets just say they're a bit scary and I don't think I'm gonna use them again.
To use it you have to grab the outer collar while it's spinning (it stops when you grab it but it's still very unnerving) and slide it back. Then you grab the spinning tool (Which also stops when you grab it but still scary) and take it out.
Putting it back in is worse; with he outer collar in the retracted position, you slide the collet back in (And keep it dead straight as you do so, I didn't and it binded up, pulled my nice Jacobs chuck out my hand and threw it on the floorCould have been a lot worse.). Then you have to hold the tool in the chuck while you slide the collar back down, but as soon as you move the collar, the tool will spin so you've got to hold it in place (I used a hammer) as you do so.
There's also quite a bit of play in it, a long drill will probably have up to 2 mm wobble at the point.
Basically, it's terrifying, inaccurate and no faster than stopping the machine. Oh, and the smaller of the two doesn't engage properly (I think the drive dogs inside it are worn).

I guess it was designed for belt driven machinery where stopping the spindle would have involved slackening a belt or stopping the whole line.

Them's the onesThese of Ebay?
.
This is the smaller one in pieces, they're very simple in construction.
The collar has an internal taper that presses the two drive dogs (The woodruff key looking things) through the slots in the body for them to engage with the collet.
