Does anyone know anything about Magna Hoop QUICK-SNAP have you them and what do you think of them, are they any good!!!!!!!!

I've got the Quick-snap for my EP-4 (equal to the MB4). I like the fact that you can make use of the free arm of your machine for things like pockets, large or small, wash mittens, trouser legs, sleaves, baby items like onesies. Happened to do a couple of wash mittens last Friday. You have to be very careful in checking whether the design fits the hoop, but they work great. You'll have to support heavy items.
I hardly ever use it for things that can be done by hooping stabiliser and attaching your project too it, like fleece, towels, leather, card stock, as I prefer the sturdiness of the attachment of the hoops on two sides.
