2 of my Hydros Optical Sensors have failed (I blame Tom) so I reached out and they're going to warranty them and replace (at my request) with Float Switches.

Sorry.

Did they make you cut the cords and send photos to prove it?

He's asking for that. I haven't yet but I will. It's not really a big deal since they both only read as "WET" they don't do me any good.

It seems to be the round ones that are failing. The square ones (newer design?) are doing fine. I've had one of the squares fully submerged in my ATO reservoir for over a year at this point and it's going strong. One round one in my DT for about 3 months and it failed.

Not a big deal but rather petty in my opinion.

My square ones are fine as well, except the tri-level one and a good RODI cleaning seems to have fixed it.

That was Ehiem's policy on heaters many years ago, not sure if they still have a lifetime warranty ?...

We have some air cleaners with lifetime warranties that used to require we cut off the cord and photo it but they dropped it after a few years and just replace without question now.

They probably figured out that a soldering iron and some heat shrink tubing could put it back in action pretty quickly if you're trying to cheat the system. It just rankles me a bit to have that extra, useless, step and, to me, infers an immature warranty department.
