The exercise arm band from Revere Sport is as described on the product description page
https://www.amazon.com/gp/product/B01N2TTXBG This arrived in a cellophane package containing the arm band phone case, extension and written information for warranty. Yes, this has a Lifetime Replacement should anything go wrong with it. I LOVE that this has the nice extension that is easily attached for those with larger arms. I also like that there is a divider for money, ID or keys. It has a hook to secure key ring too. This Arm band can be used for any exercise. It does have two ports of earphones, but my iPhone 7 is Bluetooth so I didn’t test the ports with wires. I also like the neoprene material. Has reflective material around the case as well as on the extension so to be visible during the evening hours. I was able to purchase this at a discount for review.
