The clear and orange plastics on my three PICOs are doing great, but the white has increased cracks on it. Two of my units had vertical cracks above the clear reservoir indicator - one of those has grown and the second PICO has a second crack coming up:
Two units also have cracks on the top of the light where the telescoping rods come in:
They all still function properly so it isn’t really an issue (yet?), but it’s something that should be addressed in future runs if it hasn’t already (I got mine early December 2020 iirc).
