I initially bought one for myself since my car does not have a navigation system.  Right after I received it we flew to Kansas to attend a series of events, for which we had rented a car.  It worked out perfectly, and we were not in the car 10 minutes when I used my Amazon app to order three more for our children.  It is sturdy, holds the phone perfectly (is adjustable), and can swivel for either vertical or horizontal display.  Definitely a worthwhile product!!!

Sturdy. Holds phone sideways or vertically and has a gap so you can charge your phone on the stand.

As some other reviewers have noted, the silicone feels flimsy ---- but I can tell you that it's strong enough to hold your phone. I run / walk several times a week and my phone has never fallen out. There's just enough room to put my ID behind the phone, and the band adjusts easily - and is stretchy, so once you get it to fit right you can just slide it on / off without opening the velcro. I rinse the band out periodically to remove sweat, but it never smells or anything. I have to take my iPhone case off before putting it into this band, but that's no big deal.

It's perfect for holding phones on its side. Still good for vertical just not perfect. Everything else I love!

It's great! Well made, doesn't feel flimsy or cheap. Holds the phone securely and the bottom is easy to open/close. I love it so far!

This is a great holder,  it fits on my bike  handlebars very well, and is very sturdy when riding.  Others have said that their phones have fallen out,  I would have given this 5 stars but there is some room for user error,  you have to make sure you snap the phone in all the way.  It's sometimes hard to tell if it's snapped in on all corners.  But as long as you snap it all the way in,  your phone is safe and sound!

Cell phone holder is very sturdy holds the phone vertical and horizontal securely and doesnt allow the phone to slide. Perfect just what I needed.

Reasonably sturdy. Easy to attach to windshield, and stays firmly put. Felt liners inside pincher ensure the handset won't be marred or scratched, which is good because the pincher grips like a bear trap! In my opinion this device will hold phones other than a Moto X 2014. My friend put his iPhone 6 (clad in a mophie) into this holder and it too stayed clamped securely despite it being much thicker. He's going to order one these too, after seeing that. The vendor maintained very good email communication with me as they sought to know whether I'd be okay with a substitution to black instead of the white shown in the picture.

I am very happy that this holder has not broken or shown any sign for wearing/tearing after 1 month of use.
The holder attaches securely to my belt (using Belt clip) and I can easily remove the phone(LG CF360).

It holds my cell phone in either portrait or landscape orientation very well. It has a soft, rubbery feel, but it is ridged enough to not be flimsy.

strong, sturdy phone holder. It's easy to install. I've had it for about a year and it hasn't fallen off or budged from the car windshield. It's fully adjustable, but it does have a limit on its angles.

Tip: the best way to install it cleanly is to clean off the glass first so that it'll stick without all the dust and debris.

Very durable and holds phone perfectly.  There are no gaps around any of the edges.  It's not real thick, but it's not too thin either.  It protects the phone well.  I've even dropped it a couple of times on accident, and the phone doesn't move.  It's very high quality and I can tell it will last a long time.

It's highly functional, because you can adjust the holder in many different ways/directions to meet your requirements. When I first received it in the mail, I was worried, because it was in its smallest form, and it looked like it would only hold a phone. But the various velcro tabs allowed me to adjust it to just the size I needed.  I always feel like my radio is secure and snug. Plus, this holder looks nice and stands out among the standard radio holders you find most people have. Would definitely recommend.
