"After suffering with Migraines for over 30 years I decided to give these a whirl after a recommendation from a friend of mine so I purchased one of the magnetic bracelets roughly 5 months ago. It been 5 months of pure bliss with this on, not a single episode of migraines, no illness or anything. I can't believe it if I'm honest it's 100% my best friend right now where as before it was one of the many many boxes of Nurofen I had stashed here, there and everywhere just in case I got one of my migraines. But 3 days ago my world was shook when the clasp broke while at work and without my knowledge it fell to the floor and got run over several times by a tarmac roller, the clasp was broken and one of the links was badly bent, to be honest for what it went through I expected more damage, these titanium bracelets are strong. Anyways I contacted MPS with my dilemma asking if they sold single links and clasps, they responsed the next day asking how many I needed to which I replied and then the very next day 2 new links, a new clasp and a new fitting machine arrived at my door free of charge no questions asked. Now that is amazing customer service to go with an amazing product. I can't recommend this company and their products enough, it has without a doubt changed my life for the better. Thank you "
