I received the (new)? Raypak Digital Copper Tube Bundle 010060F in a timely manner. That was good. I opened the box to find that there was some goopy stuff all over the header side of the unit and I could see the outline of the header that had been removed, which is ok because that part was not supposed to be included, but you could at least clean up the mess you left all over it. Also ther was a lot nad I mean a lot of tiny copper shards, shavings all around and inside every tube. It took me over and hour to get them all cleaned out, so I was comfortable that these tiny copper razor blades didn't end up in my pool or down the slide where a kid could get cut up from them. I could tell it wasn't used only because the copper was shiny copper and not the green coroded color, but what a mess. A lot of the copper fins were smushed and I had to bend them back to where they could be effective in heating the water.
I gave 2 stars because of all the extra work I had to go through. I would have given only 1 except that it showed up on time. It is now installed and working, so there's that too.
