“Nice and functional plug strip with USB chargers but difficult to wire with the minimum space within the channel. I put six in a kitchen. Not sure what the reasoning is for the switch on them possibly for the USB chargers. I broke one of the switches while attempting to snap in the channel. You need a lot of patience to install these. I put these in at a customers request because they thought Task Lighting plug strips were to big. I like the look of these and would install again but only if they remove the switch feature which.”
