Check out this Quad Lock VS Knockoff Quad Lock video (I’m not affiliated with this channel). They broke an iPhone 13 trying to pull the Universal Quad Lock Adapter from the Quad Lock handlebar mount. I say that the 3m adhesive Quad Lock uses is pretty strong.
Here is my take on this subject:
My phone is close se to $1000.00 USD. Do I really want to be carrying it on my bicycle without a full case… nope… I have a tendency to drop
my phones and break them beyond repair… and these new phones with wireless charging capabilities make the chassis even more delicate.
