Title: Current design has problems
Review: The concept of the extension handle is great, but no matter what I try I can't get the wheels to stay on the axle. I have tried pushing hard, even gluing, but as soon as you put it on the ground and try to roll it, the wheels fall off. So it is totally useless for the expected purpose. They need to either but screws on the axle and the wheels, or provide a more secure meth9d of attaching the wheels, such as putting holes on the axle and use cotter pins.
Is the review positive or negative?
