After testing the QuQuyi 1" ID x 1-1/4" OD PVC tubing across multiple scenarios, I've got some strong opinions about this four-season hose. Let me break it down for you.

The Good: This tubing saved my RV plumbing project when big-box stores failed me. That "perfect fit" moment when it slid onto my fittings was pure magic. The flexibility is impressive - it bent around tight factory offsets without kinking, and cutting to length took literal seconds with basic scissors.

Real-World Performance: As a water level indicator in my workshop, it performed flawlessly. The clear transparency made monitoring easy, and the UV resistance held up against my sun-drenched windows. For low-pressure applications like drain lines or weed sprayers (though buy extra length!), it's surprisingly adequate.

The Ugly: Unboxing revealed concerning manufacturing quirks. Those permanent creases from shipping? They never fully disappear. The advertised OD measurements felt deceptive - mine measured noticeably smaller, making some connections sketchy. And that mysterious Chinese ink printing? Looks unprofessional on what should be clean tubing.

Pressure Test Surprise: While rated for 145 PSI, I wouldn't trust it near that limit. During testing, the tube felt alarmingly flimsy under moderate pressure - more like a temporary fix than permanent installation material. The lack of rigidity means it collapses easily if bent too sharply.

Final Verdict: It's a budget-friendly option for specific situations where exact sizing matters more than premium quality. Keep expectations realistic - this isn't industrial-grade tubing, but for seasonal uses like winterizing or temporary setups, it gets the job done with some compromises.
