Yes! I have one. I haven't used it a great deal, and I have no experience of other coverstitches, but I am very happy with it. I have had a bit of trouble with one of the needles constantly coming unthreaded, but I did figure out why (and can't for the life of me remember now!)
(I sat on the settee admiring the beautiful job I'd made of the hem of my t-shirt a few days ago, then realised that I hadn't actually made that t-shirt myself...)
