ozonator is $120 but there is a online coupon for $10
I bought 2 of them one for my sis and one for me and they work great
one thing bad of about it is that it has a max 30 min timer for safety purpose i guess so inorder to ozonate the oilve oil you have to twist the knob 100's of times
since to make properly ozonate the olive oil they recommand ozonating them for 24 hours LOL but its a good product iam satisfied
