I should rely upon the existing bad comments. Indeed, the quality of this product is very weak for the price. I live back because I did not even manage to insert the tubes in the feet ... impossible, even insisting, to make them return. Waste of time and money. Not recommended so. And given the state of the product package (just the cardboard packaging and nothing else) I think even that article you sent me was an article reconditioned. Holes in the cardboard, torn carry handle, large scotch on closures and sides .. It's been really pro.
