Sure, on paper, this seems great: a platform where you can grab old photo gears at a discount, or even trade in your old gear. The first 2 purchases I made on mpb were great and straightforward. I didn't use the trade in option and purchased old lenses that were as advertised. Then I tried the trade in option, and everything went bad. The first trade in, the team pretended my lens had fungus, same lens was estimated as "like new" by the same team 3 weeks before. They also pretended the lens cover was missing, which wasn't the case. Because of that, the purchase value decreased a lot and I had to pay much more than advertised to receive the gear in exchange. The second trade in was a total scam. DHL came to my home 3 days later than planned, and finally, my lens got lost. It took more than 30 days and tons of long emails for the team to react. A bit of fighting too, the team pretended I didn't send the lens. I finally get reimbursed a part value of the lens that went lost. So, if you're looking for a serious company, IMO, think again and go somewhere else. I might have been lucky 2 times, but this clearly seems to me to be a complete scam. Grabbing a bargain is always nice, but fighting with liars or people who don't care to lose your lenses or cameras is clearly not worth it.
