Query: Terrible product - makes grinding noise

We got this mobile as a gift. Unfortunately, this mobile is very poorly designed. I came to check the reviews to see if other people were experiencing the same problem of the mobile getting stuck spinning. Turns out this is a common problem. The issue is the canopy is separate part and must be attached to the top. If the canopy opening is not perfectly circular then it will rub against the main assembly causing it to get stuck and make a terrible grinding noise. I have tried rubbing Aquaphor as lubricant and tried widening the canopy attachment but nothing works. Luckily, we have another mobile as I will be tossing this one in the trash.
