    I found these snow guards at price below other brands. I’m normally skeptical of lower priced items on-line, but I took a chance. I’m glad I did. They arrived quickly, and when I opened the box, I could tell they were of quality. Wasting no time, I took one of them up to my roof to see how it fit over the seams. The slot depth and width were perfect, and the installation took maybe a minute using the Allen wrench. Later that same day, I installed the rest of them in no time. We’ve already had our first snow, and it hasn’t moved an inch. I highly recommend these guards.
