Product was advertised as "about 304g". Product as received weighed close to 400g, which is a significant difference (about 30% heavier) and is therefore not "ultralight" as advertised.

Seems of good quality. I have not tried it yet. Can't say if it is heavy or light-do not have nothing to compare or to

My first Kally Uno seatpost thought having bought their stems I knew what to expect and no regrets also with it. Actually bought this over PRO post with a single side screw which was about the same price but had reviews of being finicky to keep adjustment and also had big white branding. Overall I prefer no-frills parts which just works without being fancy or require toouch attention. The rear screw extends a bit so check if your saddle has clearance, mine does. The front screw is flush with a barrel.
