I recently used this Hot Wheels race car backdrop for my nephew's 4th birthday party, and it definitely added that extra 'vroom' to the decorations. The 6x4ft size was perfect for creating a focal point behind the cake table, and the black-and-white plaid flag design made for some really fun photo ops with the little race car enthusiasts.
The material is lightweight polyester - easy to hang with the included rope (though I wish it had more grommets). During setup, I noticed one corner grommet started pulling through when adjusting the tension. Pro tip: Handle gently and maybe reinforce those corners with some duct tape before hanging if you're using it outdoors.
While the print quality is vibrant and the racing theme is executed well, I wouldn't call this a high-end backdrop. After one party use, there were some noticeable creases that required steaming (as mentioned in the product details). It's more of a 'one-event-wonder' than a reusable decoration.
That said, for under $20, it absolutely served its purpose. The kids loved posing in front of it, and it really tied together our race car theme. Just don't expect heirloom quality - this is very much a fun, disposable party accessory that does its job with decent style.
