I had no idea this clip was going to be so difficult to open so theoretically I can't use it for its intended purpose but it's good to have in case I need it for the fixation need will be very strong. I need something lighter to compress. I needed both hands to press and I need something I can only press with one hand. Beautiful and durable, looks well made and for the price you can't go wrong. I give 5 stars but I can't use it.
