M spring

Have been using the M spring for afew months now. So far so good, might be better if the dimensions inside clamp be slightly thicker to prevent slight twitching of the clamp(personal ocd).

M Springs rocks!

Have been using them for almost 2 years and they still work perfectly as day one! Love them so much that I'm buying as gifts!
