"Got the white finish and setup took me less than five minutes. Brought it to a tailgate and it performed. Took a day longer than estimated to arrive, no big deal. I'm in Kansas City, MO. Solid deal, no regrets."

"Chose the king size and it does exactly what it's supposed to do. I keep it in the car for road trips. Instructions could be a bit clearer, but I figured it out. Would buy again."

"Came earlier than the promised date. I've been using it daily for about two weeks now. The strap is a little long for me, easy enough to adjust. I'm in Kansas City, MO. Worth the money."

"Bought the starter kit and the battery easily lasts a full day of use. It's handled my daily dog walks without issue. Wish it came in more colors, otherwise great. Shipping was quick and the item delivered."
