Its a metallic camera, outside is plastic. except shutter-button (being still unstable) using cable-release there is no problem with the plastics.
they should rather double the quality control than double the prices.
if they can produce a desert-proof kalashnikoff then they should also be able to produce a perfectly working pancam. "perfect" is a shame for a newer version of the 202 but with a worse lens.
the problem is displayed elsewhere on my pbase-account and here in apug.
enter horizon s3-pro in google.
buy a 202 from a trusted camera-repair-shop.
