What are the odds to received two items from same manufacturer (but ordered & received at different times) & both have issue with them? Well one, I ordered & received MATO Tiger 1 metal wheels & it came with a pair of ŕoad wheels where the curve is much shallower than the rest. Probbably from different tank. However, after little tinkering, I managed to get it work without falling off while driving. The second one, I ordered & received MATO metal gearbox with ball bearings (I don't remember the version). One of the gear missing a C clip. The small part where it should hold the C clips also missing. Don't they checked when packaging or during QC? Well I got it to work by putting a tape so that gear doesn't slide when moving.

These was a couple years ago. I don't know why I didn't talk about it. Seems I just like to keep it to myself. Do I have a problem? Well that is for another thread in another forum.
