Product came in good shape, in good time. The wire is pretty thin. I was concerned about it handling 240 volts. It came a metal clip strip to anchor the wire. Clip strip had no directions, and I didn't like the idea of metal against the wire. So instead, I used fiberglass drywall tape. The directions did say to insulate the floor from below. I used 1" foam board. Installation is simple enough; It is just a lot of work. I had 590' in a 14'X14' area. Up and down, up and down. Let me tell you, It is well worth it! Once I got it up and running, the floor is cozy warm and the room is always comfortable. A great addition to a room remodel.
