Yes, I have one ... it converts all the household peelings and waste raw food into lovely compost and worm tea (worm pee !) both of them are really good - the compost is really pure - fantastic for raising seedlings if you mix it with some leaf mould and the worm tea gets diluted 10:1 and is really good plant food.
I got mine in the autumn and in all honesty they didn't do a lot over winter... they really got going once the weather warmed up in spring and they are booming at present. I like to see them doing their work and they are making loads of baby worms at present.
To be honest - we only use kitchen waste to feed the worms ... we still have compost bins for the garden refuse they are not up to industrial quantities with these home wormeries ... this is the one I have (although its gone up a lot in price since I got mine !).
