Okay, I have a product suggestion.
Your current product is wonderful, but tries to be a jack of all trades to make things easy for everyone.
But nobody else will EVER use my phone dock, so I don't care about them, I care about me.
I love my wife, and she may drive our Tesla any time she wants, but she has an iphone, and the dock is setup for my Pixel.
So, instead of having rubber flaps pushing my phone towards the middle of the dock in the hope that the charger port will line up with the cable poking up, give me hard, metal guides.
Make the side slots have a smooth, metal guide instead of a rubber flap, and make the guide adjustable with a screw mechanism from the top. This will make my phone fit in EVERY time.
I have no problem getting tools out should I get a new case, or a new phone. But I want an EXACT fit on my phone EVERY time, not just some rubber guides that really just stop the phone from wobbling once I have slotted it in place.
I would like to point out how well your current product is made, I just want something more exact.
