It's not cheap but for the length its able to do i thought there would still be some flex or wobble to it or it would be too heavy to use easily. but this thing is so light and the tolerance of the build quality are so good that at full length it is rock solid. I've seen some reviews say it is heavy, but i dont know what those people are thinking. for somethig made of metal thats 3 meters long i could hold this thing up for ages. Maybe those peopel have never picked up a weight in their life, i dont know but anyone who is a boom operator i think this is the lightest you will get before paying for something made of carbon fiber.
The mechanism on the adjustable lenghts is strong, and easy to use.
