No it is not. The adhesive on the base is designed to allow you to place it where you like, when you like, it’s repositionable. In the event that the adhesive starts to loose hold strength, you can simply run the base under cold water to clean away dust and dirt it might have accumulated. Let the base air dry, or wipe with a lint free cloth. Repeat as necessary for the life of the product.
