Rated 5.0 out of 5.0 by Good product for a good price. I found the thermostat built into the product to be a good selling point. February 7, 2012
Rated 4.0 out of 5.0 by No busted pipes It's a heat tape! Working so far. Should consider some lengths between what is currently offered. January 17, 2012
Rated 5.0 out of 5.0 by good quality tape Make sure you read the instuctions before instillation. I installed one last year and did it wrong! DUH!! I had to change my installation on the pipes from last year!! My fault completely. Other than my mistake it was a great product and ez to install.The hardest part was covering it with rolled insullation.I have a small crawl and the old home isnt piped for ez instillaton.

Rated 5.0 out of 5.0 by Hummingbirds will love you for this! I wind the cable around the glass container of hummingbird feeders and secure it in place with tearable duct tape, It keeps the feeders/liquid from freezing when the temperatures plunge, so over-wintering hummers are able to continue feeding.

Rated 2.0 out of 5.0 by Instructions or package does not tell you that the product does not work in an above 38 degree environment. Product only works in outside environment below 38 degrees due to nonadjustable thermostat. Instructions or package neglects to mention that key fact. I had to find that out by researching the reviews on-line. The product seems to be fairly well made and probably works for certain applications. It will not work in any indoor to outdoor type installation. I will be returning the product shortly. February 13, 2014
Rated 5.0 out of 5.0 by Use for a heater hose on my RV water hose I got this installed on my hose and it seemed to be working very well, however before I had a chance to really test it out and use it, I had to disconnect my water hose and shutoff the water, due to frozen water in the line. I will be hooking it up again, once the water line has thawed. The hose I had it installed on already had frozen water in it so that really didn't help. And then, the water supply line froze, so I just diconnected the hose. We had -20 temps and now we are still in the 20-30 range, so I may have to wait until some warmer days to test this out again.

Rated 5.0 out of 5.0 by Just the right product Information based on shipping and right type of product. Have not used product yet and will be next winter before use. April 15, 2014
