What is worth waiting for

In the first delivery several parts and the base ring were missing (the product picture the lowest part) did not fit into the fitting (probably was warped). The package also looked like ever eaten - so ripped and dented and stained. This is of course everything first annoying, but there are return / exchange / repair. Contact with the seller was also very nice, though a bit bumpy: I should choose from a lot sent me schematic drawing those parts that were flawed or missing, these would be sent to me. The problem: Some of the parts that were missing were indeed seen in the picture, but were not called (What can I say "I want that thing in the middle of the left - the missing fact?"?). The next problem: I did not know why the base ring does not fit, yes. Incorrect base ring? Bent fitting? So I asked them to take back the whole thing and send a new me. Even that was not a problem because the contact with the seller was really nice as I said. Two weeks after I returned the faulty set, I asked then, when I could expect the replacement. I was then informed that the processing of the complaint could take up to a month - again very annoying. When I again asked that I simply send a different and complete set, it came suddenly and two days later the thing then there was. Looks good, for the price is also really high quality and handles well. I hope it holds. I would have given otherwise 4-5 star, but the back and forth, studying parts lists and schematic drawings and the many mails provide stop but for a small Störgefühl.
