Very flexible, with one handle to tighten all connections at once. The universal turn signal holder is finely adjustable and holds most of my turn signals except the rear ones. The magnet is strong enough to provide a secure hold. But if you're buying this, chances are you're a locksmith, so be quick to knock out the adapter. It would be nice if Noga put a 1/4" protrusion adapter in the universal holder. It wouldn't add much to the cost.
