Question: they say 6-7 inch spacing.  is that right?  Seems like all the others are 2-4 at most.
Document: Price is great, product works great, MAKE SURE TO GO BUY A ROLL OF NICE ALUMINUM DUCT TAPE BEFORE YOU START THE INSTALL. One roll will be plenty for the job if you tape down approximately 50% coverage of the cord. Only 4 stars because o the tape shortage. Buy with confidence.
If I had not noticed that the spool was labeled "1000W" and had not recalled that it should be "1750W" then I would have installed it. Then when I got one half of my room done and realized that i only had one half of the heating element that I needed... It would have been a disaster.I have requested an exchange. I will update my review after I receive a replacement.Update - 2 Days LaterAmazon exceeded my expectations. I requested an exchange.
This product cost less than 1/3 of what heating mats would have cost. Make no mistake, this is not nearly as easy to install as mats, the cable is thicker and must be embedded in mortar. Also, it would have been nice if they had included about 3 times as much tape. All in all, I am happy with the cost savings.
That was sort-of to be expected since the error was on Amazon's side. The surprise was a follow-up email that apologized for the mistake and upgraded the replacement item to next day / Saturday shipping. That is excellent customer service.I received the replacement before noon on Saturday. This time it was exactly the item that I wanted.
I wanted to express my frustration. I ordered GudCraft SWS1750W. This is supposed to include a 1750 Watt spool of heating element that will cover 160 square feet of space. Instead I received GudCraft SWS1000W which has a much shorter 1000 Watt spool of heating element to cover 80 square feet and is much less expensive.This is very disappointing.
