Does the job, though the metal pins are a bit off but mainly because of the umbrella bottom shape

These are great... But really big and if you think you can fill with water the kite that comes with them says you cant use water if you live in a place where the temps go below zero. Took ages to fill with sand but great once done.

Great product. a great addition to my Parasol.

This does a fantastic job of holding my umbrella.. only problem is the size

Does the job. We filled ours with water. It does take up a lot of ground space though.
