I’ve used this hose for over a year in both summer and winter. It stays flexible no matter the temperature, and I haven’t had any issues with cracking or hardening. The silicone feels smooth and doesn’t collect dust. Works perfectly with my pressurized CO2 system.
Sonia Knox –
Compared to my old PVC hose, this one is much more reliable. It doesn’t get stiff in winter, and the silicone is safe for fish. Installation was easy and the hose holds pressure well.
Sophie Watson –
Good quality and durable. The hose is soft and doesn’t wear out quickly. I noticed no leaks after several months of use. A bit expensive, but worth it for long-term aquarium use.
