    Hard to go wrong
  

*by S***I on Reviewed in the United States on June 4, 2020*

When a product is done right for the task; it's really hard for it to be wrong. This is a line-set designed for mini-split AC/HP applications & there's nothing wrong with it, whatsoever. It is exactly what I expected it to be.I will say (should anyone be wondering) that the fittings are the heavier-duty style and much less prone to splitting due to water leaching into the bell & freezing. The insulation on this type of line-set is easy to work with & to pull through holes than the old-school foam type, and since it's melded together, it really suits Mini-split installations.I was not expecting to be blown away, and I wasn't; but that said... there's nothing bad to say either.Good product, packed right, shipped fairly quickly, and matched it's purpose quite well. It was just as advertised, and I had no issues.  Overall, nothing bad to say > good review!

    It works.
  

*by S***D on Reviewed in the United States on June 25, 2018*

This arrived in slightly damaged packaging with some small dents in some of the insulation, but it worked well. I installed it in a cooper&hunter ductless mini-split, used nylog blue lubricant on the threads and flairs, and torqued it to the specs in the installation manual with a digital torque wrench and it seems to work well with no leaks (the unit has been running well for over 10 days now.) I ended up not using the plastic hole guide thingy as I didn't have a hole saw large enough for it. Instead I 3d-printed one that was 2.25" O.D. with 2mm thick walls. The tubing was a tight squeeze, but doable. I also only needed one of the 4 included rolls of rubbery non-sticky tape stuff. The line hiding kit I purchased (not from ductless air but one that's half the price) didn't allow for a 4" bending radius. This is the reason for the ball of duct tape at the top. I hope the HOA doesn't notice...
