I recently purchased a neat little 3ooW bass cab, but at 40+ kg, some transport seemed appropriate. Hence, I ordered and received my Smartcart, and very nice it is too. It is indeed foldable and flexible; and thus perfect for my needs. In fact, perhaps one else's too - my 84 year young Mother - who is often guilty of moving large items, etc., which are too heavy for her.
Therefore, as she was visiting today, I decided to show her my latest purchase. She loved it; so much so, that she asked if she could have the Smartcart. How could I say no?; and, as she pointed out, I could always order another one, couldn't I? This I will do shortly.
In the meantime, all I can add is that allegedly, or so I am told, the Thomann Smartcart really is excellent for moving heavy plant pots and, it seems, big boxes of groceries and lots of large household objects. It's also easy to store in her utility cupboard.
