VUP Detachable Bike Phone Mount, All Screen Friendly and 360°Rotation Silicone Bicycle Phone Holder, Motorcycle Phone Mount, Fits for iPhone Xs Max/Xs/X/ 8 Plus/ 8/7/ 6s Plus, 4-6.5" Phones

Pros: Detachable, Slim profile, Rotates.Cons: Does not stay secure when riding over a few bumps.I really wanted to like this product. The phone holder fits my iPhone X like a glove, it's not difficult to put on and allowed access to all ports and buttons. I wanted something that I could attach to any phone case. (previous phone holder needed to have a permanent fixture to the case so I had to change out cases whenever I wanted to ride.) The phone holder easily detaches from the mount so it's great when you need to remove it for a few minutes and then put it back on. Being able to rotate the phone is also great when using your GPS. Unfortunately the deal breaker for me is that whenever I would hit a few bumps the mount would slowly find itself out of position and my phone would end up facing the pavement. My handlebar is not a straight bar; it becomes more narrow from the middle towards the outside so I don't know if that's what causes the slippage or of its because of the material of the handlebar/phone mount.

When I opened the package, I was a little concerned since it looks smaller than my Samsung Note 9 - about 2 inches shorter than the length of my phone. But it actually stretched out to fit my phone! When mounting on my handlebar, the piece of plastic to push through the locking mechanism was a little bit hard to get through. Just a little bit wiggle is all you need. No matter how tight you turn the dial, you will still be able to move the mount around the handlebar but the mount looks sturdy enough. I haven't tried this yet on the road so I will update after a few rides.Update 8/13/19: Unfortunately, this product did not serve me well. When mounted on my handlebar, the weight of the phone spins the mount so that the phone is not perpendicular to the ground and I can't see the screen anymore. Also, it worries me that my phone will get out of the silicone straps. Changing it to be mounted on the stem, it will go to the left or right so it's not at optimal viewing angle. Tightening it does not help. I have since removed it from my bicycle.

Very easy to install and has not moved at all. It just barely fits my galaxy s8 in an otter box which is why I only have 4 stars, sometimes I feel like it might fall out but that might just be my own fear. It's very sturdy and for the price a great deal. Works just as I need it to.

Easy to use and holds phone very securely, even with a pop socket installed. Easy to adjust viewing angle. It's really been a nice addition to be able to easily access and monitor Map My Ride while biking.

Love this phone holder , switch it between motorcycle and car in minutes , quick release for phone to remove from bike to go in stores , get gas , bathroom etc .. holding up well , use it a lot

It worked as it supposed to. I used on center goose neck which is larger diameter so I had to work a little to get the strap far enough up to catch the locking mechanism but once I did it secured properly. The straps hold the phone very securely and is easy to get in and out.

Works like a charm. Great price.

Dude these things are amazing, I can pop my phone in an out with ease, and I feel like my phone is devote at all times. The only downside is on my iPhone 10 the mount covers the top corners of the display, and makes it hard to swipe down the control panel to pause music, or see past notifications. Small complaint for an awesome product.
