Horrible to install. My Bluetooth range is around 30 feet which is fine by me - I can cover most of my apartment without losing signal. The 4 was perfect Its not like I need it to climb Mt. I could sneeze on it and make it fall over, let alone try to hang clothes on it. I was a little confused by the strap but after about 30 mins I figured it out. Dang it dang it dang it! Easy to apply & not too hard to take off! A light duty bike carrier. I would give 5 stars except for the tag issue.
