I sent several pieces of equipment, very carefully assessing their condition. I trusted their expert judgment, but a couple of hours later I realized that I had made a mistake with it. They downgraded my Panasonic Leica 12-60mm from Excellent to Good. Without any additional comments in adjusted quote!! They claim that the rating like Excellent or Good only reflects the cosmetic appearance. It took a lot of effort to get any info from them. As mentioned in the last explanation: "adjusted down to "Good" owing to some internal marks within the optics of the lens" Very detailed explanation!! The day before in the chat they claimed that "scratches on external elements". Two conflicting assessments! They took 72 euros off the price of my Nikon 180mm lens. In adjusted quote was stated that "moderate fungus". Today's information was already a little different: "-€72 adjustment for minor fungus" Bravo!! The fungus has already decreased during the holidays! If things are going like this, it will disappear completely, you just have to wait a little. In this case, with the Nikon 180mm, they did not lower the rating - very confusing! I bought this Nikon 180mm lens 4 months ago on eBay from reputable photo equipment seller from Japan in Mint condition without fungus. I doubt that a "moderate fungus" has developed in the meantime. They downgraded my Olympus 45mm lens from Like New to Excellent and no additional comments in the adjusted quote on Friday. Today I received information that: "adjusted down to "Excellent" owing to light dust and moisture within the optics". It should be noted that I owned this lens for 4 years and only used it in warm and dry weather, the rest of the time it was in a warm and dry room at home. Where does the moisture come from? In my 30 years of experience with lenses, I have had no problems with any moisture because I know how to use lenses. Total inconsistency in rating lenses. First one judgment, now another explanation. These are very convenient ratings - "minor fungus", "minor moisture", "minor dust" - they can be used in almost any situation with lenses. I just lost faith in this company. It looks like they work very sloppily or just think only about their own benefit. I admit that it was my mistake to trust their "trained specialist" judgment. They insist that the transaction has taken place and that it is irreversible. Be careful with your choice when doing business with MPB, think twice so you don't regret it later. They are not customer friendly. Apparently, their magic business is based on this, - to create trust in "some trained specialists" who evaluate the things. And to abuse people's desire to get money fast. Unreliable service.
