I have had some for a couple years. They make a great base for stands like a Guido's Web.
Mike hit on my experience pretty well. They are slower than a set of sticks but are very quiet and stable. I just slung them over my shoulder and I can see where some may find them a little bulky but not bad imo. I eventually purchased 2 sets since I ended up using 4 for my GW base and wanted a set to climb with also. I recently purchased a set of Muddy Sticks and they work great and will probably be my "go to" system.
If you research the CPs and decide they might be for you, let me know and maybe we can out a deal on a set.
