A perfect addition to my Warwick Triumph Lite EUB. It's heavy, which gives it stability I can trust, even if my EUB is in the most extended position. The range of the upper extendable part is enough to accommodate any position of the EUB. It came assembled so I had no problems with the upper part twisting and making the EUB fall to the floor (as I've seen in some other comments). At home, I even keep it with legs not fully extended and it's very stable that way (in the corner of the room, with no one to even bump it. In this form it does not take as much space as I feared. While when I go out, I extend it fully and then it's very stable. Overall: sturdy, well-build, stable.
