bought a 100gpd unit and all the bits from them, easy to install and full support via email. Have been using it now for 4 months and its brilliant, makes my water at 000ppm with no problems.
In fairness the 100gpd is too small for me now as i've gone more or less over to wfp for all my work, I am going to buy the upgrade kit for £50 which makes the water faster and reduces the waste.
I bought some spare filters from them, very cost effective and good delivery.
very pleased with my Osmotics set up.
