It heats up, but it kinda takes its time.... I wanted it warm within 5 minutes... But it took like 10 before you felt anything... 20 minutes before I liked the way it feels
Right price works well. My contractor did have some issues making it lay flat after he poured the mortar on top before laying tile. Nevertheless, it has been working well with even temperature under my feet for the 3 weeks I have had it. I will update if there are issues.
Super easy to install and its made in America. I called to ask how many amps it draws and I was on the phone with a friendly smart sales guy in a few seconds not a call center. Its 1.5 amps on full draw by the way. Great product and great company. Thanks for making it in AMERICA!
