Housing degrades and breaks in 1-2 years
on November 1, 2014
Works for awhile but... we have had these for two years. We originally purchased four, but are now down to one. Each of the three broke in the same spot: where the plastic housing connects to the base. As you will see in my photo, the plastic here is extremely thin, especially given that most of the torque loads are here. It seems sturdy enough when you first install it, but the plastic seems to degrade in the sun and after a year or so and then it takes very little accidental force to shear this off (I broke this one merely changing the battery - see photo).They work fine, but sooner or later that batteries need changing or someone will bump into them, and the poor choice of materials and poor design on the base means you will be uninstalling the pieces and sending them to the dump in just a few years.
