Product appears to be exactly as advertised. Both connections were as expected, so I had it charged and installed within 30 minutes (I had pre-installed all the connections to the hot water heater supply line). Unfortunately, this product just sits there ready to absorb any surge, so one cannot see it doing anything. It sure looks good, and doesn't leak!

It is a bit larger than I imagined. I had to wait longer for it to be delivered than I thought I should have to, but it was during the early days of Civid lockdown.
