Just installed this line set for my mini-split AC and overall, it did the job well. The copper pipes were the correct size (1/4" and 3/8"), and the flared ends sealed perfectly—no leaks so far!

The insulation is THICK. Triple-layer protection seems legit—embossed PE film, weather-resistant foam, and extra cotton. No complaints there. The included accessories (drain hose, straps, wall cap) were handy too.

BUT… the wiring wasn’t UL-listed like advertised. Had to swap it out myself, which was annoying. Also, the copper pipes feel softer than expected—not sure about long-term durability.

For the price? Good value if you’re okay with minor quirks. Just budget extra for UL-rated wire if safety matters to you.
