it works shockingly well even with my old usb 2.0 adapter. i bought it recently for a roadtrip and it not only kept my phone's Bluetooth working but also added a decent amount of charge over the course of the drive. i honestly have no complaints. i used the vent holder and not the dashboard suction and it kept the phone firmly in place. I'm pleased with this purchase.

Solide, pratique et très efficace : on peut l’accrocher à peu près partout dans l’auto et ça charge très bien n’importe quel cellulaire. Très recommandé!

two issues: 1. if phone is heavy like I have fold, it will not be able to pull it up or hold it strongly. 2. as it cannot pull it up, the phone doesn't wireless charge always, as it miss the wireless spot.(though it has two) solution: you need to hold the phone at specific place then press buttons to close it, then it can hold the phone at wireless charging spot and could wireless charge. but it is not single hand friendly usage in such case because you need to hold phone for few seconds and then press button with other hand. for light phones it might be fine.

Love this. Works with Samsung S21FE. Auto grips phone when placed in unit.

Works for one of our phones, the other is too large to fit easily, and wireless charging works for it but intermittently

good quality
