I've been curious about this too so I googled a few reviews and most people said it took forever for them to receive the product (4 weeks to a couple months.) Other than that most people are satisfied although it takes a little bit for dogs to get used to because of the sound it makes and the vibration of the tool.
I've read a lot of negative reviews about it. People especially complained how cheaply it was made. I don't know about your bassets, but mine has very thick toenails, so I doubt the peticure would do much good.
I'll second the suggestion for a dremel... I think they cost about the same and you can get one a lot faster than a peticure.
