I have to say that I wasn’t a fan of it. I have 5 steps leading up to my house, and the cart was very difficult to maneuver up the stairs. The Velcro straps never seemed to work well, and on one occasion my harp even tipped to the side and fell off. I got so fed up with the cart that I just tossed it in the trash.
I found a 3-wheeled cart that is a little bit more expensive, but well worth the money. The wheels make it easier to get up stairs, and the straps are a lot more secure. I know that the McLaughlin family sells these carts out of Arizona, and there are other manufactures out there that make similar models. I actually believe that Salvi makes a cart like this. Below is a link to the Atlanta Harp Center, which sells these carts.

Hope I helped!
