I purchased two Ventmatics back in 2013. They were disappointing. Both faucets exhibited leaks and the finish of the metal parts was mediocre at best. They were returned for a refund.
I took a look at the ventmatic website today and it looks like their finally back on track after a prolonged legal battle with Perlick.
The New generation faucets look pretty good.
Unfortunately, the recent product review by Brulosophy has sparked alot of interest so the current lead time is 1-2 weeks for their faucets.
I may have to give them another try.....
