Excellent Quality Print, Poor Quality Magnets

I order these magnets with the company logo to give to my clients after they receive the final product. I was hoping to have something that would remind them to come back to me for more photography services, hanging right on their fridge. The idea was great, but unfortunately, the magnets on these aren't strong enough. Many of my clients have commented on the uselessness of the magnet as it won't hold anything to the fridge. I found the same testing them on my fridge at home. Like most people, we all have things we hang on our fridge (lists, todos, etc) that we use fridge magnets to hold. The poor quality of these magnets means they won't hold much of anything and results in my clients placing them on the side of the fridge, not the doors. That defeats the purpose of being front and centre, to remind them of my services. Please address the issue and use stronger magnets. I will refrain from ordering again until there is a change.
