I use the deck for transporting my large bass cab on my RockNRoller cart. Without the deck, the cab would fall off. So it is a must-have.
The deck in two parts is annoying to transport in a car: two loose parts of considerable dimensions.
The four wooden blocks underneath each part, for locking to the cart, are poorly designed. It takes minutes to try, retry, replace and turn around to find the right way to click on the bottom of the cart. I had to adjust them by scraping off some wood. Now they fit in seconds.
The metal "locks" on these wooden blocks are useless to me (I never use them). The firm should design some kind of click-on system.
Nevertheless, I'm happy to have the deck because the RockNRoller cart would be of no use to me without the deck. That's why I think this deck should be sold together with the cart, not as an accessoire for an extra charge. I cannot imagine using the cart without the deck.
The build quality is okay: strong enough to carry heavy weights.
Once you have done some work on it, this deck does what it is supposed to do.
