I got a pair of these last week and posted my impressions in the gear review thread.
Basics for me were that they were on sale for $50 (plus shipping), ended up weighing 8.7 oz on my scale (120cm version) and fold down to 12.6", all of which were AWESOME. However, I didn't like how they felt, so I'm sending them back (unless someone here wants to try them for $55 shipped...
They are no longer on sale, so if someone wants to try them, this is your cheapest option. I'm happy to send them to a fellow BPLer rather than back to the store, just let me know soon, since I'll be getting them out of the house by week's end, one way or another.
