I used Poles and Holders for years and love Corky's service, but I switched to Flagpole Buddy about five years ago and I don't think I'll switch back. I like their products and quality better.
Corky at Poles and Holders and Christine at Flagpole Buddy both deliver 11 out of 10 service, but I think Christine's products are better.
The ladder mount is my favorite. I can do it from the ground instead of going on the roof every time, and the mount is much stronger because it holds in two places.
All of us in camp had broken multiple Poles and Holders poles in the wind, but my Flagpole Buddy is the only one in camp that hasn't broken.
