Allright, here’s a short review of the Biowave case in combination with a SP Connect Universal Interface (and Handlebar Mount Pro MTB).
Positive:
- Great fit, the FP4 slots into the case without a problem
- Raised border around the screen, protects it when not aiming for single rocks
- Buttons are still easy to press
- Pleasant surface, feels organic for lack of a better word
- The Universal Interface has bonded nicely to the case
Neutral:
- As expected quite a bit bulkier and heavier (case + interface ~43g)
- Somehow even less grip than the aluminium frame
- A bit finicky to remove
Negative:
- Without a screen protector that raised edge interferes with gesture controls and that is already starting to annoy me
- No indication where the case was made, but a similar iPhone 11/12/13 case sold by the same company (under a different brand name) is clearly marked as “Made in China”
- Fake Amazon reviews, or how come 4 of 8 reviewers all reviewed that iPhone case mentioned above and somehow all have switched to a FP4 now
TL;DR: I’m quite happy with the case, seems well built and works great with the Universal Interface. Time will tell if that combination survives a few thousand kilometres of bumpy roads, I’m optimistic it will.
Wouldn’t use it as an always on case though, way to chunky.
Since it’s a bit hard to remove I’ve instead bought a Universal Phone Clamp for a family member, that would be my recommendation for light cycling use, but only really usable without a case.
