Review on Cal Van Tools 119 Magnetic Holder by Norlan Pippinmd

Available in two hole sizes: 1/4" and slightly larger. Magnets on the back are small but seem sufficient be (if barely) to hold the strip on a vertical metal surface.However I only filled 1/4 of the holder so this may not be enough in the future.I would like to try other holders as I suspect there is something otherwise it's better out there.
