I purchased the K&F Concept set with 2 quick release magnetic adapters for my DJI Osmo Action (compatible with 3/4/5 Pro) and am overall happy with it. Strengths: Effective Quick Release: The magnetic function combined with the clip lock is very convenient and fast. It allows you to quickly switch the camera from one support to another (e.g. from harness to tripod) without wasting time. The clasp feels secure and I had no problems with accidentally unplugging it. 1/4” and GoPro versatility: The inclusion of both the standard GoPro type 3-prong attachment and the 1/4” threaded hole is a huge advantage. It makes the Osmo Action compatible with a much wider range of 'traditional' photographic and video accessories. Construction and Materials: The materials (aluminum for the fixed clips and high-strength nylon for the body) give a feeling of strength and reliability. The impression is that they are accessories that are meant to last. Improvable Aspects (which justify the 4 stars): Space/Weight: The adapter adds a minimum of thickness and weight to the base of the camera. It is an inevitable detail given its function, but it should be kept in mind for those looking for maximum lightness or who have accessories that work at the limit of their buoyancy capacity. Magnet accuracy: Sometimes the magnetic alignment, while facilitating the first grip, is not always perfect at the first stroke to trigger the clip. However, light pressure or a minimum of adjustment is needed to ensure complete blockage. Conclusions: If you use your DJI Osmo Action in different situations and with various supports, this kit is an almost indispensable accessory. It greatly improves the ease of use and expandability of the camera. Despite the small room for improvement, the construction quality and functionality of the magnetic release make it a purchase that I would make again. Recommended for those looking for versatility and speed.

Fits very well, unfortunately wobbles a little bit more than the original DJI holder

great little product, the magnet and clips are secure and fit perfectly into the slots.the price is perfect for what you get.this mount functions perfectly for motorbikes.

As good as DJI half the price and you get 2 no brainer

High-quality bracket, which does not hide compared to the original, must definitely be recommended
