This phone holder does support many phones of different sizes since you can adjust the width. However, it's best suited if you do not have any cases on your phone. I use Otterboxes and even the slimmest one will fit, but screws can become loose if you're on uneven surfaces and will jostle loose and your phone can fly off. That's what happened to me on a pebble road. It has the secureness at the bottom if you sit your phone upright, but I scoot on the Emove Cruiser and had mine sitting on top of my handlebar horizontally and constantly make sure it's not loose on the side where it holds my phone. Now, I broke my S23 Galaxy Ultra on my own and was sent the S24 Galaxy Ultra and it doesn't fit as snug with a case, so now I cannot use it. I can take off my case, but I got a more secure Otterbox and it's not exactly made to constantly remove and put back on just to sit in my phone holder. That's the only reason for a 4 star. It is very sturdy and fits well on my scooter. It's too bad I can't continue to use it.

Son rides this to work most days. Smooth ride, battery holds good charge. He lost some screws (he wasn’t great at checking them) but was able to buy replacements from Varro. So far he has had one flat tire, but auto repair shop was able to plug this type tire without needing to remove it. Big improvement over the Segway Ninebot he used to ride.

Hi. The holder works except that the prongs are too small and the phone easily falls out. I use a rubber band to secure it from Amazon.

works great..no issues or concerns of falling off when riding.

This phone mount is excellent. I bought another one for my bicycle.
