Item arrived expeditiously, appropriately packaged. Replacement was straightforward and without incident - requires removal of the controller board enclosure for access. Could tell the old sensor was malfunctioning by the higher than normal fill level (it was filling to overflowing, luckily there is an overflow drain). Good quality, same as OEM, fully functional after installation.
Solid stainless steel rod, stainless nuts and lock washer; flexible silicone multi-ring insulation spacer prevents false triggers from splash or condensation; original sensor lasted 9 years, this one should exhibit equal durability.
