Hey Team. Door Anchor: This set DOES include a door anchor. My first thought when I saw this product was "who the hell would buy Park cleaning brushes?" Yes, I agree that Park tools are generally very high quality and worth the money but. So now I love all my Crocs and dont have to give the ones away that dont fit! I would says if you are taller than 53 you would need the long option. Haven’t tried to drop it active or put it into water, but the Anker Sound core seems like it could take a lot of abuse if needed. Instead of having 3 different wires to plug into everything, I have a little station that I can just put everything on with one cord that charges the dock itself and I don’t have to fuss with, it just stays plugged in wherever I choose to leave it (usually but my bed on my night stand). I used 2 cups of water to give it a waterproof test and it seemed to hold up. You dont need the app to use those features. Note: there was one on a well-known “bidding site”site that was much cheaper but it was coming from China and I didn’t want to wait on that slow boat.
