Be sure that when you install them, place them in the control panel how you want them, then pour boiling syrup, water or fruit juice over them, then quickly close the lid. If you follow those instructions, your cherries should last you many seasons.

I think I found the problem.  I took apart my two chronic stickers.  One of the had really big plastic nubs left over from the casting process and the other had small shards of glass inside as well as those nubs. 

I shaved the plungers down and they seem to fit fine for now.

We get these pre-assembled, so you must have gotten one that slipped by.  I don't know where any other material might have come from, but I doubt it was glass.  Maybe some polycarbonate flash that slipped in at the factory.. 

The thing that still is a little odd is that you said they were fine initially, and then they weren't.  So something still must have changed after they were installed?

I don't know if it was glass for certain, but it was hard, sharp and clear, could have been a large grain of sand.  I didn't look to close, I just flicked it to the floor. 

I think the wood may have constricted a bit or the plexi shifted after a few weeks enough for the burs to catch.  I'm not real worried about it, they're smooth a silk now, but it has been a bit cooler recently.  I'll have to see what happens when it hits 100 outside.

Total OT, but water is quite rare in that the liquid is denser than the solid.  Plastics, metals, CO2 (dry ice), etc get smaller when going from liquid to solid as a general rule.
