Xprit 8.5'' All Terrain Off-Road Adult Electric Hoverboard w/Bluetooth Speaker. This is listed in the UL 2272 Certified, https://productiq.ulprospector.com/en/profile/34769/fkis.e485669?term=hoverboard&page=1
I’ve had this for a couple years now and have only road it a handful of times. It is a great way to get around but as I get older there are better way to get around. A few scratches on the bottom but besides that it runs great and the speaker is as loud as it was on the first day I got it. $200 for this bad boy. Feel like that is a fair price because brand new they are listed at $230
