The first thing I noticed was how sturdy this is. It's strong. Sturdy. Seems to be well made. I purchased my unfilled. Prior to purchasing it, I had a bag of sand laying across the legs of my umbrella. I was surprised by how much of that bag was able to fit in the new sandbag. It holds a lot !
Having said that, I believe this is worth mentioning, as well. I've been thinking I might like to purchase a 2nd bag. I close the umbrella at night. But, last week a storm came up, while I was away. There was a sizable wind that came with it. My neighbors noticed the umbrella seemed to be swaying. So, they came to close it for me. Great neighbors, huh ? I think a 2nd bag would make the base more stable & be heavy enough to withstand that kind of wind. We get some serious wind around here.
ProsAgain, it's well made. Even with sand, from filling, the zipper went right up. The clasp is sturdy,and well secured to the bag, as well. Putting it around the pole, at the base, was no problem either. It's compact and easy to move. No messes either !
ConsThis is not, so much, a 'con'. But, it does require 2 people to fill this. One to hold it open, shake it down, & one to pour. If that's how you're doing it. I suppose 1 person could scoop smaller amounts and do it.
I was trying to do it alone. I actually stopped a young man walking past my house and asked for his help. Most people are willing to help, if it doesn't take much of their time, or cost them anything. : ]
