I bought 2 Dri boxes to protect the Z-Wave smart switches on my outdoor Christmas decorations. Achieved goal of keeping internal wiring dry (for now). However, they have one unpleasant quality. The sunken tips collect the rain and 1/2 inch of water collects in them. That's when the new, no big deal. In the future, as they grow old, any small crack or hole will turn the top into a funnel that directs all the water inside. Bad planning and design. You have to drain the water from above.
