It works, if you are lucky and merciless enough to get it in
It took some truly brutal hammering to get this thing into my steel steerer tube. If the steerer was aluminium, i'm afraid it could have split. I needed only 2 cm of additional steerer tube length, but stopped while this extender was 4 cm out of the tube, to minimize risk of breakdown. And my steerer tube is not tapered from the inside (i.e. getting narrower from top to bottom), as seems to be not uncommon problem when attaching this extender. The inside diameter of steerers seems to vary a lot. The manufacturer of this extender should make very clear which inside diameter of steerer is compatible with this extender.

On the other hand, the extender did the job for me and seems to be solidly attached in place until the end of times.
