I'm very disappointed with this product. It worked fine for a few times but now it has malfunctioned. The crank box half popped out of its place and of course I can no longer open the umbrella. I'm trying to fix it, but the product is made so cheaply that the screws of the box won't even unscrew. I've been trying to reach customer service, but there's been no answer. I would like to return it or at least exchange it for an umbrella that works! Very disappointing. I also think that this product's average 4 star review might be hyped up artificially, because scrolling through the reviews all I see are bad ones. I'll keep trying to contact customer service to find a solution, but I'll never again buy this product or anything made by them.
