Review on 🏃 Running Armband for Samsung Galaxy S21 Ultra - Waterproof Sports Phone Case Holder for Runners by Guled Hamilton

I am very happy with it. It's big enough to store my Samsung S21 even with a case on. It has a small lid that closes and velcro to keep the phone inside. This is a feature I haven't seen in other styles. Has 2 side slits to adjust the fit. One for smaller hands and one for bigger hands, plus an extra strap you can add for really big hands. There is a key slot although I don't use it. I'm still amazed at how well it holds my heavy phone!
