I originally left a 1-star review because on a bike ride my iPhone 6s came out of the holder when hitting a bad bump. However, I have to correct that review. I now believe that I failed to fully engage the lock switch underneath the holder at some point during the ride. With the lock fully engaged I cannot cause the iPhone to pop out even on much worse bumps. I've tried over and over again, and the iPhone stays put. When you're wearing gloves it's harder to feel and it's possible to push the switch but not fully engage it. You have to pay attention and make sure it's FULLY engaged and that the holder cannot open.

I can't really blame the manufacturer for this. So my revised review is 4 stars. It's not 5 because I'm still not very happy with the way it mounts to the handlebars. At the tightest point where I can still fold over the latch, there's some slippage during riding. I prefer a metal clamp with screws. But the holder does hold the phone so long as the lock is fully engaged.

I should also note that the manufacturer immediately contacted me regarding my 1 star review offering a refund and a replacement. That's what made me take a 2nd look at the holder and fully test it rather than just throwing it away. They will stand behind this product.

The thing is a PIA to mount, because things that will hold onto a bicycle or motorcycle are sturdy and don't come off. The tradeoff is exact. It does exactly what it's supposed to, I didn't lose my iPhone Mini manualing and hopping curbs on my Mtn bike. I almost never use it, but *when* I need to use my phone or a device on my bike, I use this thing. It works perfectly and as advertised in every single detail, including the 'lock' being hard to switch. It's got to be that way. A reasonably intelligent stone will see this as soon as they use it. Perfect discount 5-star Amazon item.

Bought this after buying and returning a cheaper model at my local bike shop. Glad I got this. It's a great phone holder. Does the job even across really rough roads and trails.

I only wish the bed the phone sits in had a depression for the camera lenses. As it is, the phone sits in the cradle crooked and doesn't feel like it's totally sitting in the cradle. To even up the holder, I'm using one of the extra bar pads that came with the holder. I place it between the bed and the phone. That causes the holder to hold the phone more snugly. Problem is, I've lost two of the three pads....

I like that I can firm up the pivot ball tight enough so the bed sits still, but still loose enough that I can adjust it while riding. I also appreciate the locking mechanism underneath. Nice touch!

My wife and I just moved to a new house and bought a couple of Aventon ebikes to take advantage of the bike trails in our area. I use the Komoot iPhone app to see where to go. Having this holder is awesome for the Komoot turn-by-turn directions. The only negative is how hard it is to lock and unlock the phone in the holder... not so much how much pressure you must exert but where the little red lock is on the back... it seems like it would be better to be a little higher up near the top. Otherwise, it has been a great addition to my bike!

I've installed this on my eBike that goes about 50mph, which will work depending on the size of your phone. It should work if you have a large case, but if you have a thin or taller smartphone, depending on the brand/model, it may have gaps on the bottom edges. Again, it depends on the profile of the phone and the case you have on it as there are slim to bulky impact resistant cases.

The holder and how it mounts to the handlebar is solid. It hasn't moved at all. But the clamping of this design either fits or does not. OnePlus 7T with a medium-sized case fits tightly and hasn't had an issue. In contrast, if I placed my OnePlus 9 Pro with a thin case, I have a little over 0.5" gap that I had my phone pop out when I went over a large bump the other day. It's an older phone so I didn't care it got scratched but be aware it "may" not work for all phones.

The clamping design should have an independent opening ratio as not all phones have similar size ratios, which causes large gaps if you have a tall smartphone.

But with that said, if you have a phone that fits, it works amazingly well. If it doesn't fit, know you'll have issues with your smartphone possibly falling. It's probably not something you'd want riding a motorcycle. What would help is a secondary silicone strap like some mounts have, which would alleviate that issue.
