I used Enviroshake once. Decent product I guess for the appropriate application. They went on almost as fast as wood shakes, cutting them was a little more work. Last time I did wood shakes on a hip, I would run them up the hip, then cut them all off at once. Not Enviroshake, we had to cut each one individually, and it's plastic, and slippery on other surfaces, so a PITA lol.
