The Mag Locks are awesome!! I use them in both of my sxs and have had zero issues with them!! The magnets are super strong and dont ever seperate from my helmet.
PCI were super fast in their shipping during the holiday season and i would highly reccomend them to anyone.
Be aware that when purchasing the hose side only, the also come with the docking magnet. I was not aware of that when ordering and ordered the docking magnets seperately so money spent that wasnt needed.
