This product is light and very cheap, but even with all the clamping screws tightened the camera still moves a little. Furthermore fixing the small plate on my camera (EOS 100D) frankly unsatisfactory or is hardly suited !!! There same, even with a strong tightening, the plate can still turn on itself !!!! I did not really trust this product and would buy me another store rather than the net. To top it all, the delivery time is 9 days, dismal for a premium purchase !!!!!
