This umbrella is perfect. Super nice and sturdy. There are plastic elements like the crank and the slide to lock mechanism but overall seems to work really well. The only reason I gave 4 stars rather then 5 is because you have to buy a base cover that you can weigh down to keep the umbrella from tipping over when open (or you could bolt to the ground). So youre looking at approximately 90.00() additional for that. Otherwise great buy!
