Used these for my picture wall and all good for 3 months. The pictures then started falling off the wall with only 20 out of 83 staying on wall. Bunnings good and gave me replacements. I put up to 6 medium ones on 6x4 picture weight in 68gms - I put heaps on all the photos. 4 months later they r all falling off again. Glue that's holds the Velcro parts are failing, not the glue to wall or frame. Absolute rubbish product that has failed twice now. Do not but this product.
