HOLD FIRE, I THINK THERE MAY BE TWO PRODUCTS BY THE SAME NAME, WILL CHECK. MINE HAS TWO SIDES AND WAS ON QVC UK BUT IT'S NOT THE ONE ON THE FURMINATOR SITE.
I have this, I got it at the ideal home show after seeing it on QVC but there it was just £15.
It does work effectivly and I should think that if you used it often it'd stop sheding all over the house but I only use it occassionally.
Wherry loves it, makes her go all floopy

However it obviously only takes out loose hair so it stops shedding everywhere but with Wherry she still has lots of whispy bits left over so still needs stripping/clipping. I din't have the same effect as on the telly but then I suppose it depends on the dog's coat.
In all I wouldn't spend the QVC price (though at least then you can test it out) for the results we get with Wherry (worker so shorter coat) but for £15 i'm not dissapointed.
I think they have a website, I know I had a re-order form for the £15 price but goodness knows where. They are a scottish company I think.
Also, the police (one area, not everyone) use them for their working dogs and they pay about £13 a piece so they must be ok

(Yes, we had a long chat
