  1. Muller Geldenhuys (verified owner) –

    Water comes out at 0ppm. Tank does exactly what it should.

  2. Nadia A. –

    Straightforward and works exactly as promised. I fill from the tap, the resin strips the minerals, and the water comes out at 0ppm – my windows dry spot-free with no effort. The tank is heavier than it looks once it’s full, so don’t plan on carrying it far. Resin lasts me about 6 weeks of residential work. Delivery to PE took a bit longer than the 3-5 days they advertise, so plan ahead when you need resin.

Bought an aluminum waterfed pole from Window Washing and I am super impressed with the build quality. I find the quality far exceeds the Chinese poles imported and supplied by many other companies throughout South Africa, believe me I have tested them all out for our solar cleaning company.
