But what really shocked me was but today, when I first held the plastic part in his hands. It was immediately apparent that two locking lugs were sitting on the inside of the aperture a little wobbly in the ring. When assembling these small parts then fall with some bad luck the first time from the panel and must be sought consuming. If that does not happen, that will make this experience later than the first or second disassembly. In addition, these small plastic parts are very heavy into enforce returns to the ring and hard to fix. So you can be sure of one thing: With this little querulous one has so long stress until they land somewhere after a few weeks in the dirt and untraceable.
I can not understand that genius has designed this moderately complex components and come up with the catch. One thing I can but more so, that discourage the product - prefer to buy from Canon and live with the feeling of having spent more than 30 euros for a stupid piece of plastic!
ADDENDUM:
Seller responded very positively to my request and offered to return, that the purchase price will be refunded without any required return! I was initially assumed that I would have to pay the cost of return shipping. This service seller found you class. That does not change the characteristics of the product, but clearly the bad feeling to have thrown money out the window!
