Review on DEWENWILS Extension Water Resistant Adjustable Compartment by Stoner Fulton

I bought it in spring and used it outdoors all summer until the end of October. I connected an outdoor fountain to it. It has never stumbled but when I opened it to take it off. it had almost an inch of water in it. It was placed on my deck so it was never submerged. All gaskets were in place, cables fit snugly. When I first set it up. I thought this thing was waterproof it's so well made. I do not think so. The one I hung vertically to connect my pendant lights spilled water when I undid the first few latches. I am very surprised at the poor performance.
