Saves time and mess
This thing saves a bunch of time and mess. And they know it cause they charge a premium $$$. Its probably 30cents of plastic. You could easily make at home if you had the right tools/skills. Also had to drill the hole out cause its extremely difficult to push caulking out as is. But it did make the job way easier. Just wish I didnt have to send them an arm and a leg for their price gouging.
