Review on 🏎️ Enhanced Power Slot Racing by Joysway by Ralph Banks

I have a question about this slot set. I bought it about a week and a half ago and was very happy that my kids could play with it. When I first looked at the description, which shows a picture of the USB cables, I assumed they were included. When I received the package it looked like it had been opened and used. The decals were already on the tracks when you can see on the box that there is a decal sheet that needs to be placed on certain tracks. I had a DC cord, when I plugged it in it didn't work. It was very disappointing. I'm willing to give him another chance. My question is, if I buy it again, will I get an unopened box? Is a USB adapter included? I am willing to change my rating of the product if I have had a better experience with it.
