Let me start by saying, this chiller is a BEAST. After testing it with my 100W CO2 laser, I can confidently say it's worth every penny. The cooling performance is stellar – maintaining temps between 16.5°C-18°C during marathon engraving sessions.

The build quality immediately stands out. Those heavy-duty steel brackets in the packaging? Genius. The power cord seats firmly (unlike some knockoffs), and the compact design means I can move it solo – a huge upgrade from my old tank-like chiller.

PRO TIP: Spring for the warranty. While mine's been flawless, some users report setup hiccups. The included hose clips are mediocre – I upgraded to heavy-duty ones immediately to prevent leaks.

Real-world performance? Game-changing. In my Texas garage workshop, it keeps my laser happy through 8-hour workdays. The 6L capacity means fewer refills, and the R-410a refrigerant handles heat like a champ.

Watch out for: The manual's confusing (find YouTube tutorials), and it doesn't include laser connection cables. Also, the water inlet's too small for standard aquarium heaters if you're in a cold climate.

Bottom line? If you're serious about laser work, this chiller's reliability and cooling power justify the investment. Just buy direct from Cloudray for better support.
