Cheaper postage! I make sure the area and suction cups are thoroughly cleaned before application. One of the four legs was drilled in the wrong place (pictured) making this "bench" entirely useless. It comes with a dual carabiner which is easy to connect to my backpack loop and fits perfectly in an accessory pouch. Btw had this for 8 weeks. I knew Id be doing a lot of walking and having the built in arch support would be a bonus. Definitely Recommend This Seller I really love how cute the case is, the main downsize at least in my case is that the top part of the case is constantly coming off which I think is a big part because the purpose of the case is to protect the product. I am not mad enough to test it in reality, but in my experience, I have had to charge it only once in the past four weeks. in vain.
