Bought this for my Blackmagic Production Camera 4k About a year and a half ago, used occasionally. Few cosmetic marks can probably be found on the rails and the cage but nothing that would alter the performance of this cage. The cage is made of metal and is extremely sturdy. This piece of kit has been super helpful over the duration I've had it.
I did buy this off eBay for £88.99 and it was imported from China (luckily I didn't have to pay import duty) I am located in the UK so you can expect this to be delivered within a couple days and won't have to worry about any import charges.
