Pros: We purchased this product to save money. The great use that we came up with was to mark all of our building piping under the snow during the winter months. The typical markers that are used for this purpose are about sixty dollars each. We were able to purchase driveway markers and these clamps they work very well we put reflective colored tape on the poles so we would know if it is a drain or LP piping or any type of electrical.
Cons: Really i have seen none for this product.
