Nice offer! You know you can peel that ollin part off and easily mount on a new case for your new phone? No reason to not reuse it. I my my own version that centers over my telephoto lens since Ollin does not. Great way to reach even further with photos.
Or even reuse the part to mke your own regular Ollin case for the non telephoto lens.
I bought some of the same 3m double sided tape Ollin uses to make sure it sticks great.
