-> The supplied Velcro keeps better than the upper part of the hub housing.
I must say that the device hanging on the hub, itself carry no weight on the stroke because I hold the cable by cable ties beneath the table that really only the gravitational pulls down the hub.
In this respect, 3 stars, because the stroke fulfilling its core function, but the workmanship defects are so serious that even a 5-star rating possible is missed.
