I havent bought one of them yet but i havent heard of any problems yet though either.I might buy one just to check it out.As for the magnet go to radio shack and get the 1/8th for like a dollar.They may have 1/16th or 3/32nd wich will also work.Just remember to check wich side trips it correctly by passing it under the hall sensor and then use a black magic marker to darken the side so ya dont glue ,epoxy,or jb weld it upside down.
