I'm delighted. Perfect device to attach a rear view mirror to canopy support on my pontoon boat by bolting a piece of wood as a transition. I think it could have been a little more perfect if the knob which tightens the clamp was a little more robust, perhaps like that of a regular C-clamp.Short of making a whole new bracket from scratch, and If I hadn't found this product, I would have had to return the mirror since it didn't fit anywhere else.
Thank you for your feedback

Excelente calidad, acabado impecable y las gomas para no maltratar superficies son muy útiles.
Yo lo ocupe para sostener una base para audífonos y control de play, pero puede servir para cientos de cosas gracias a sus múltiples agujeros para tornillos, ya que de esta forma no se tiene que perforar, maltratar o alterar de manera permanente los muebles o superficies.
