IPOW Motorcycle Phone Mount, Bike Phone Mount Holder, Universal Cell Phone Bicycle & Motorcycle Handlebar Phone Holder, Compatible with Smartphones 13/12/11/X/XR/XS/8/7,Galaxy S20/S10/S9

I specifically bought this product for the Pokemon Go app. Whether it's getting steps to hatch an incubating eggs, travel to poke stops or track down a specific pokemon; the mount works very well.The mount fits securely for both 5 and 6 inch phones. Tested it out on my Nexus 5 and Nexus 6P. There's also a rubber band that attaches to the corners for added grip. Make sure you twist the manual locking mechanism after attaching it to the ball joint so there's no turbulence while ridingWhen you hit speed bumps on the ground, the mount may change the angle slightly depending on what your bike rolled over, so you have to manually adjust the angle after impact. Your phone does stay on the bar though so no issues on it falling off your bike as it has a secure foundation. While casually riding it won't vibrate as it's very stable and easy to view (until you hit that big bump)Overall very impressed with the bike mount. And as always be aware of your surroundings ;) 4.5/5**Update: Purchased another bike mount for my brother who also plays Pokemon Go and this one is a lot cheaper (as of this updated review): Bike Mount, Liger Universal "SuperGrip" Bike Mount Handlebar Holder for iPhone 6S 6/5s/5c/4s, Galaxy S5/S4/S3/S2, HTC One & Other Smartphones & GPS Holds Devices Up To 3.5in Wide. You get to save a couple of bucks. It's the exact same thing except the brand name on the device is different, and the Ipow version has an extra interchangeable band (you get a red and black band instead of only red in the Liger branded one). So up to you if you want to pay a couple of extra bucks for a bonus band.

Would have give higher rating but rubber stabilizers are to small for Galaxy Note20 so it has no holder other than side grips which are only good not great or excellent. In addition the screw that clamps the unit to handlebars is already rusting after only a month. 90% of metal from China rusts really fast. Had same problem with other items from there, I'm talking much higher (supposedly) quality & priced goods purchased in past. They have a serious rust problem.They repaced the holder with their motorcycle holder and I give it 5☆⭐️'sIt is a nice, and secure holder. My phone fits with the case it's 17.5cm long x 8.8cm wide x 1.5cm thick which is just right. IMHO this holder will survive significant abuse or an accident quite well. It is very strong & sturdy. The locking & adjusting features are very thoughtful and useful. Would by again

Two long rides and my phone stays stable. Easy to mount. Easy to attach phone.

Update 3/5/2017:After my original review (listed below) for which I gave the product 2 stars, the seller contacted me for a free replacement and reimbursement. She mentioned that I must have received a faulty product. Given that there was little downside, I accepted a replacement mount.The replacement mount works fine. I can tighten it enough by hand so that changing the angle of the mount takes a fair bit of effort. After I installed it on my bike, and took it out for a long ride, I can say that this mount works fine when installed on a bike. Hitting bumps and potholes no longer caused the mount to move.A tight mount, flexible mounting options (fits 25.4mm handlebars as well as most stems), an affordable price and a seller (Good Assistant) that was proactive in resolving the issue made me update the rating to five stars.I now recommend this product.Original review follows:The mount is made entirely from a hard plastic, except for the elastic band. It fits my phone, A Droid Turbo in a Diztronic protective case. I definitely needed to apply the elastic band, as the clamps itself wont hold the phone.I have installed it on my stem. I like it that the clamp allows the mount to be installed on your stem or handlebar as it be adjusted to accommodate various diameters.The main problem is that the nut that tightens the ball-joint cannot be tightened enough. Whenever I hit a bump on my bike, the phone moves, having me to readjust the angle of the mount.I can't recommend this product.

I was about to complain about this item because I am shopping for a replacement, but then I saw that it's been nearly 7 years since I bought it the first time. To be fair, it spent 90% of that time sitting on an idle bicycle hanging in the garage, but for $9, I don't mind buying a second one because out of all of the versions of this product I've tried, this is one of the easiest to install & deal with. Just don't expect very high quality craftsmanship, or for it not to fall apart under heavier use.
