I've never had a pipe freeze up since I purchased it. Wrap the lines plug it in and forget about it. It has a built in thermometer that takes care of things for you where it is not a concern. It kicks on somewhere around 40 degrees though, I wish it came on around 35 degrees instead.
Products seem to be of quaility and as described... My only complaint is they limit use or reward points making them pretty much worthless... only allow a percent of earned points on new purchase... That being said they really do not effect my buying options as a option to sway me toward Vevor..
The build quality is excellent. it's much more robust than I expected it to be for the price. I installed it plugged it up and I monitored the operation every day that we had a temperature change cold enough to start it and also when it warmed up enough to shut it down. it operated flawlessly so from this point forward I plan to just leave it plugged into its dedicated receptacle. and loosely monitor it. it was money well spent and a rather inexpensive solution to what could be a major problem
I guess it works, has a thermostat to go on and off. No Light past the thermostat to tell, to the touch its cold, no heat. The water has never frozen over the cold winter. That's what I was going for. I would say yes it works.
The tiles are easy to place and worked well providing a non slip covering for a wooden deck during our snowy winters. The elevation of the tile allows snow melt to drain away from the soft mesh surface.
