## Customer Reviews

### ⭐⭐⭐⭐⭐ good quality but expensive
*by A***R on November 22, 2014*

Looks Good but expensive. Easy to install and quality was superior. I'm a general contractor and normally don't review items but this company makes good products, my only complaint is the price. I think I should sell this stuff, they must be making a killing out of this. Cheaper alternative might be gutters from your local Home Depot or something.

### ⭐⭐⭐⭐⭐ Works perfectly
*by A***R on September 9, 2023*

Worked perfectly for hiding refrigerant linesets. Snapped easily together, not sure what others were talking about... I am an HVAC professional so that might help :)

### ⭐ Open box
*by D***D on May 11, 2024*

Received a box that had been opened and then resealed. One side of box was torn open (in shipping?). Missing the bag of clips to fasten line-set to the cover with zip ties. The product itself seemed to be what I expected, looked easy to install and decent quality. Returned to Amazon and awaiting a refund. Will try to reorder and see if I have better luck next time.
