I googled "shed monster sheltie" and it came up with an amazon review from someone that used it on their sheltie...
"3.0 out of 5 stars De-shedding tool
This de-shedding tool works alright on dogs with the correct length hair - if their hair is too short, or too long for the specific de-shedding tool, it doesn't work all that well. I have 3 dogs, with 3 different types of fur - it takes too much hair off of my Sheltie, and not enough off of my short-haired dog.

I had this in my hand at Walmart last night but decided against it. There should be no quick way to groom a sheltie..I spend 4 hours a week per dog, and if you use a pin brush, slicker, and undercoat take, you rarely need anything else (unless you show or something).
