Very Expensive for what it is.
It’s just a small stainless steel metal enclosure for the filter. No magic. The heart on the system is the 60$ filter which could be enclosed in a different way. There are hot water metal enclosures that cost 100$+.
Works great for now. If you’re trying to avoid plastic in your filter then this one still has plastic filter, fittings and tubing. So it’s a wash.
