Removable belt pocket - Mystery Ranch Removable Belt Pocket Backpack Accessory

I love everything about my Metcalf pack but was a little disappointed with this pouch. Yes, it's well made and does it's job. There's two improvements I'd like to see: 1) make it about a 1/2 inch longer so that my Galaxy S7 would easily slide in and out of the pocket. 2) Change the attachment system, it's got two unnecessary straps with snaps that are made to go on other products with MOLLE webbing and it would be nicer to have an attachment that you can take on and off your wast belt without having to un-thread it each time.
