I've used this tripod for about 30 years, and I frequently think of it as my best investment ever because it is so small, light, foldable in a flat profile (it can fit in a coat jacket), and quite solid even with a medium format camera and a large lens. See: https://www.stpaulguttercleaner.com/

I still haven't found anything that could be improved!

The tripod itself is lightweight and sturdy. Legs lock up tight.

The leveling will release suddenly and you camera will be cockeyed. it is a great concept poor execution. You are always wondering if your camera will fall off.
