Don't worry to much about it , its an instrument that looks to be , being used and loved .
I discovered a tiny dent , ( 10mm x 3mm and <0.25mm deep ) on my iStar OTA a while ago , don't know how it happened ? and only I know where to look to find it ,, these things happen .
But dropping a TV 17mm Nagler 1 metre to cobble stones ..
, that sux big time .
