So as I said, they hold air and do so quite well. The pump is outstanding. Mounting can be a bit tricky. Once you get the hang of it though it's not bad. Little learning curve.
Like quality/price. Received today 10+ days after placing order. Dislike-Ad and write up pictures a big beautiful travel bag as included... There is NO travel bag shipped with product......
Product works great. Very stable and sturdy after installation. The directions are absolutely awful. The manufacturer should have clarified installation instructions and possibly have a video link.
