Things I liked:Way better than cartridges. Things I would have changed:Use braided metal lines and highest quality fittings available. What others should know:First one leaked right away. Second held up for a while, but leaked at threads, extra teflon tape fixed that. Now, it's leaking in the fitting,, I can't fix that.
For this much $$ you'd hope they pressure test these things first. If it leaks, it's useless.
