Brand... Ultimate add-ons. 16 bucks. Comes from UK so I got 1-3 day shipping for 7 bucks more than standard shipping. Got it in 2 days can't beat it.
This is hands down the best one available. Been using it for a week it is amazing. No vibration. Was using gomadic before, junk Lost my phone 3 times.
Fits perfectly. Says for i9100 only but it is a perfect fit. There is a waterproof one too but don't need waterproof and wasn't sure it would fit since it closes completely, I bet it would though.
Strongest one available trust me I've been looking. Needs to be for 150+ MPH! Has two actually bolts that clamp on instead of one weak plastic nut like most others. The handlebar clamp feels like aluminum too, not positive but I don't think its plastic.
