IN SHORT: The product seems valid, at the level of other more expensive ones, but it has some design choices (most likely, related to costs) that are important to know to avoid unpleasant surprises; in my case, I returned the product for the problem shown in the photo (details later), but I bought another copy because the quality/price ratio was still better than others. The protection is solid, like more expensive products, and has a design that, at least for some details, may be preferable to others: it offers 3 standard attacks with 1/4 screw (easels, selfie sticks, etc.) and 2 cold-shoes, useful for accessories such as any microphones or lights, unlike most competitive products that offer only 1 or 2 1/4 attacks, and usually 1 or 2 cold-shoe; in addition, it includes a magnetic base (not very powerful) compatible with Insta360's ARCA quick-release attacks, and with the standard (convenient for selfie-sticks and easels, only in “static”, not action); these are the main reasons why, despite the problem shown in the photo, I decided to re-buy this product instead of passing on the competition: 1/4 attacks offer greater solidity than cold shoes in action settings, having 3 in different positions gives more versatility than competing products that cost a few euros less, and also of competing products that cost significantly more. Negative notes (important): - as clearly shown in the photo, THE GOPRO/ACTION CAMERA MOUNT IS COMPLETELY UNRELIABLE: used with a bike on a paved road it lasted less than 25 minutes, then one of the flaps came off, fortunately I noticed the problem and immediately disassembled the camera before it came off completely; in practice, the GoPro attack is absolutely to be avoided in typical action camera contexts, with vibrations, fast movements, etc. (that is, it is essentially unusable for its function main, therefore.. useless) mainly due to the lack of solidity of the rods that keep the fins mounted. - 1/4 attachments have no “bottom”, and this means that, in some cases, screwing too much can actually damage the rubberized camera body; the problem is marginal, many accessories have screws of adequate length, which do not exceed the length of the hole.. but it is a good idea to be careful when assembling to avoid unpleasant surprises.
