I had a low-cost alternative for the expensive Manfrotto removable disks wanted on Amazon and I came across this one and have ordered them. Two weeks shipping time I have taken into account in the price. When after three weeks no packet / Maxibrief was still arrived, I took over the Amazon customer service contact with the seller ... e-mail came back, which I have been told that I should wait a bit. After another week waiting period (4 weeks) I contacted the sender again: The answer was 1: 1 the same e-mail as previous week. Now I sit here today, still without quick release plate. Because of an impersonal and unfriendly service and the fact that my order is not always here, I advise anticipation expressly AB to order. Because you, unfortunately, can not be awarded zero stars, to my knowledge, there is this 1 star.
