I bought my smartwatch in May 2020. In August 2020 the sensor cover came off. I was able to send it off and have it repaired at no charge.  Today, a month after the warranty expired, I was wiping off the underside of the watch with a damp paper towel before I put it on the charger, and the cover came off. AGAIN. 

I don't mind paying for repair service but the cost estimator says it's going to be $81.  To glue the sensor cover back on. AGAIN. That's about a third of what I paid for the thing.

I don't think so. What a ripoff. I'm irritated and disappointed at what a piece of junk - and what a hassle to deal with - this watch has turned out to be.
