Necessary, but should be part of the Sportube
on 13 February 2013
I wouldn't like to have to manoeuvre the Sportube without this. As so often stated here, it should be part of the original purchase, not an add-on. (Same for the lock, the tube is useless without it!!)
Other than that, it's well made and sturdy enough to do the job.
Only 3 stars because of the price, and the fact it has to be purchased as an extra.
