I purchased the hot shot dish heater based on the other review and I couldn't agree more. Definitely worth the money. I have been risking life and limb for 2 years climbing on my roof during blizzards to get the dish cleaned off. Depending on the type of snow, the trip to the top of the roof was like an adventure sport. So when I read the other review, I definitely could relate to his scenario. The Hot shot was easy to put on, again I took his advice and removed the dish and brought it inside to attach the adhesive heater to the back of the dish. Very easy to take the dish down (4 bolts) and put back up. The directions were simple and the hardest part was making sure to get it on without bubbles. Once that was done, the connections were simple and I put the transformer under my eave next to a plug in. THe next day we had a hugh storm, 2 feet of snow and the dish heater worked like a champ. 2nd best money I ever spent behind my snow blower.
