I bought and installed this kit a month ago.  Guaranteed it won't snow THIS year LOL.  I've used them in the past.  They work, but must be installed correctly for acceptable results.

The kit: I have bought Frost King in the past.  I'd say the Easy Heat kit is comparable.
The quality of the cable and plug etc. is "good".  The quality of the shingle clips and wire ties is "ok".  They are aluminum which makes them quite malleable.  The clips barely hold onto the shingles.  The ties barely hold the wires in place(due to the memory of the wire insulation).  We'll see how they perform in the weather.'

The Process: Frankly, I think the whole setup is a "Mickey Mouse" afterthought solution.  The idea of having wires affixed to roof shingles is ridiculous.  I'm sure they're going to trap debris all year long.  How does one rake snow off the roof if necessary?  How nice would it be to have electric matt under the shingles?

You'd be wise to PRE-PLAN your entire job before buying anything!
1. Know your amperage and location of your electric.  You can't daisy chain these things.  Each one must be plugged directly into a GFI protected outlet. (no extension cords)  If you're installing new electric, FIRST plan the wire coverage which will dictate where to install the electrical outlets.  Also, I'd opt for 20 amp circuits.
2. Measure carefully before buying your cables.  Don't go cheap.
I was surprised to see how much cable I actually needed.  Basically, YOU CAN'T BUY TOO MUCH!  Two years ago, I went cheap and just dropped one into the gutter and then 4' down the leader.  It was fine for flurries and dustings but quickly overwhelmed by significant precip.
Go on Frost King web site and view the instructions and formulas.  Also, take some time to come up with YOUR optimal solution which uses the lease amount of cable. For every situation, there are several solutions.

My Situation:
I have a shallow pitch roof on my 2300 sq ft ranch house.  I installed mine 16" in center and a few inches up past the soffit line.  I also have a skylight, which I "reached" up to.  I used 1(200') and 1(50') to cover one 28' section; about half the back.  That's going to max out the 20 amp circuit I allocated for the entire back of the house.
