⚠️ Limitations & Things to Consider
The width range (55–85 mm) is good for many phones, but very large phones with bulky cases might exceed it.
Spring‑loaded clamps can introduce some flex / play, especially if the mounting isn’t rigid or if the phone is heavy / there are accessories attached.
With phones mounted on the edges or with accessories, the balance / torque may cause slight droop or shifting unless well supported.
The LoPro is discontinued in some markets (“No longer available” shows up in some retailers) so availability might be limited.
