At first I had a Gloria FM10-foam sprayer which is pumping up during the 4th time explode before the pressure relief valve has discharged. Had Well, bad luck and buy one more thing. After about the same time runs the container at the bottom, at least it did not explode. Hab thought the little devices are just junk and I've bought this Comfort Prima. 3. After filling also began the container at the bottom to trickle down and the entire contents was gone. Now it was me too colorful and have sent all the devices connected to the Gloria customer service. Test Report: leakage (but that's something new, ha) Medium not suitable = PH 12 Instead I got a replacement cost estimate for repairs, which was approximately the same as the new equipment The agent used in the prescribed dilution had a pH of 11 (soapy water) In which the foam cleaner diluted disposable canister and was mixed safely dissolve thereby even after many years not to, even disposable PET bottles in which the metered concentrate was kept. Conclusion: The container of Gloria devices have therefore a poorer quality than disposable plastic. Furthermore, one has threatened me that I would have to pay, for every liter of the soapy water 20 Euro disposal if what is found in the container. Luckily everything was ausgeronnen previously anyway due to defects. The total cost of course I knocked and I see from now any supply of Gloria device on my address as trespassing. The return also I paid. I'm going to build myself such a device, but with car pump 6 bar and 18 volt AC battery and when I partially do it from scrap parts, it will survive me anyway.
