Yep, two bought, two returned/exchanged within the retailer refund period. Both were the 300xxxx serial numbers bought in new england in June. Both developed blobs and what I consider grease/ lubricant marks after several hundred shots. I knew about the issue before hand but decided to give it a go. Bottom line for me is this, how do you know there wasn,t a manufacturing issue that was caught early that they decided not to recall that will not get better but always be a problem? How do you know the problem wont get worse or morph? Two too many fundamental questions its reliability. Broke my heart, I fell in love with my Dee. I bought a canon d6 and have been quite happy wiith it. Maybe I,ll take another look at Dee in a few years. Happy shooting!
