These corners are a little hard for me to work with because of arthritis in my hands, but after half an hour, I got the hang of it. The adhesive is very strong. I only wish the corners were a little bit larger.
Actually, I would never recommend your WEB SITE to a friend because I know I ordered the right product, but got the wrong one, and when I called your customer service number they were NO HELP. Probably 75% of what I buy today is online - clothes, gifts, appliances, everything. I know how to work a web site. There was no way to verify the color of the product when I ordered it and the service rep was NO HELP.
I gave 3 stars because, even though I cannot use the product, it appears to be okay.
