Top base is the Ram, for 19cm diameter and above bar.
Very good ball rotation and durable.
The phone doesn't go anywhere whether you find a pothole or in motion at high speed.
It fits large phones like Xiaomi and Pro Max.
The middle short arm is the most convenient in terms of weight and rolling direction of the base, so as not to find the windshield.

3 stars only because the Allen screws and Allen key are 3.5mm and of mediocre quality. With a little more tightening, damage can occur. The Allen key got lost and you can't find a 3.5mm Allen key in the store

Classic base, securely attaches to any motorcycle mirror and holds GPS - mobile firmly, regardless of vibrations.
