Works well
Works really well to hold phone in place during bike rides. I have a fairly large phone at 6.8 inch display and this mount can hold my phone while in a case. I have only used it in portrait mode on the stem of my bike, but it can also be used on the handle bars in landscape mode. It has multiple holes alone the strap to allow it to fit on different size bars. Pulling the strap needs force to get a tight fit, but I never felt like it was going to break. The phone is held in place with four straps that come up over each corner. The straps do come across the screen on each corner, but it is not distracting. The corner straps also need a little force to get over the corner of a larger phone. The material has held up over time and has no signs of wear or tear. Feels sturdy and safe to hold a phone on a road bike trip. I have not tested it on off-road biking.

It’s easy and it works
I had bought my wife one of these a while back because the hard plastic one’s was accidentally calling 911 and always slipping. My new bike tracks my info and when I just touch the screen it displays the information. So I decided to get one also. Pros It holds the phone in place without any issues. It is built well and we have had no issues. We do only ride on the road so it may be different on MBT’s. Very easy to install with no tools and you can easily switch it from bike to bike. It fits multiple size handle bars. Cons It’s not the best looking phone holder but I’m not taking away any stars for that. Conclusion It’s easy, it’s versatile, it works well so what else could you ask for. For less than $25 it’s hard to beat.

Excellent - easy use and quiet
I use my phone for GPS and tracking all the time when I ride, so I really like to have it mounted. I previously had <a href="https://www.amazon.com/gp/product/B07VPGRHK6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1">this phone mount</a>, the hard plastic kind with multiple thumb screws to tighten and loosen. It was a bit of a pain but worked ok on my old hybrid. Now that I've upgraded to a road bike I needed to mount my phone on the stem (or spend $$$ for an out-front mount), and the old one was horrible - rattled like crazy with every cranny in the road and had me worried about breaking my phone, or at least certainly scratching my new bike. I've had this holder for ~2 weeks / 250 miles of riding, and so far it's great. No noise, super-easy to mount on the bike and take the phone in and out (great for photo ops while riding); feels super secure. 4 stars since I do worry about the rubber fatiguing, and I wish I could adjust the position/angle of the phone a bit more - you're pretty much stuck with the angle of your stem. Maybe they could design it with the stem-fitted piece at an angle so you could at least mount it 1 of 2 ways for a different viewing angle?

The Minimalist Mount
I’ve had numerous mounts, this one is the best by far. It’s made entirely of soft durable silicone, which is a huge plus. It holds my iPhone firmly without scratching it or the frame. It stays steady with no movement or bounce, even on rough pavement or trails. There’s no rattling at all. If you like a clean, compact mount, this one is for you. Worth the price!

A solid cell mount for average everyday bumps
has held onto my bike's bar with little fuss. It doesn't feel like something that is going to take extreme abuse or shocks, but for its price it hold well.

Best phone mount I've ever had. And I've had a lot.
Definitely is the BEST phone mount I have ever had. And I've had a lot. Some were very expensive. Hopefully the straps that stretch around the corners hold the test of time. I will definitely update if they don't. But right now, I'm really liking this. I can thrash this bike all over the place and there is NO issue. Also, as shown in the video I included, this can be mounted on the top tube instead of the stem. I was going about 35 mph with wind blowing on this thing and trying to make it wobble. You can't really see well in the video but, I was lifting that bike about 3 ft in the air and just pushing it down as hard as I could over and over. You can see it barely moves and when it finally does, it's got that nice snappy flex to it.

Okay
Not the best for larger phones. Feels somewhat secure, but when over a bunch of bumps in the role the bottom part fell off the phone and it was hanging by just the top piece. Would recommend for price based for medium sized phones on roads, but larger phone be careful.

Best bet
