Pros

Runs one shower and a sink at once in warm climates
Made in Germany with a 7 year leakage warranty, longer than the 5 years Rheem gives
Digital temperature setting holds the outlet temperature steady as flow changes
Needs no venting, so it mounts on any wall near the panel

Cons

Needs 2 x 40 A breakers and at least 125 A service, so many older homes need a panel upgrade first
No Wi-Fi or app control at this price
