These devices are designed to be inserted into the sand and provide a stable base for the umbrella. Another option is to use sandbags or heavy objects to weigh down the umbrella and prevent it from being blown away by the wind. Additionally, make sure to properly set up the umbrella by digging a deep enough hole in the sand and firmly packing it around the base of the umbrella to provide extra stability. **
