I got this product for free from 3M in exchange of my honest review. Once again I am greatly surprise with 3M products, this clips are easy to use, my only problem is that my review came after just a few weeks of using this product if this is intended for using as a seasonal one then is perfect; I would like to keep them for as long as possible on, as we speak they still holding on place. I have not tried yet to remove them so not sure about how easy this step will be or if I can reuse them.
