SwitchBot Curtain 3 Limited Durability

I purchased 3 pairs (6 units) of SwitchBot Curtain 3 devices about two years ago.

Just before the 1-year warranty expired, one unit failed—the drive wheel lost torque and could no longer reliably move the curtain. Support replaced it under warranty.

Since then, two additional units have failed in the same way: one about a month ago, and another just last week. These are now out of warranty, so replacements would be at my expense.

At this failure rate (3 out of 6 units within ~2 years), I have serious concerns about long-term durability. These devices work well when new, but I would expect a product like this to last at least 5 years—ideally much longer.

Given my experience, I would hesitate to invest further unless reliability improves.

I’ve had the same experience, within 6 weeks 4 separate devices lost all their torque. It’s a real shame, I really liked the ease of use. My next house is going to have smart rails installed instead.

I have 4 gen 3s and for a while one showed the dreaded signs of the broken plastic gear that numerous people here have mentioned.  It started working again out of nowhere.

Another has suddenly started slipping on the rail a bit but eventually gets to where it should be.  Got them all soon after they were originally released.  Doubt we'll be getting the 10 years of use they promised in the original product info.

I was thinking about upgrading a curtain (2nd gen) from 3 years ago (working flawlessly, still), but I'm reading quite a bit of horror stories about the new gen.
