I knew I had a quality product on my hands when I noticed the rubber strip just in front of the clamp's hinge. As far as I can tell, its only purpose is protecting the clamp's spring, preventing anything from getting pinched in there. It has nothing to do with basic functionality, or with advertised features. It just makes the product better. This isn't one of those products where you wish the manufacturer had spent an extra nickel on better components; nor where you take it out of the packaging and realize that it was designed to just barely fulfill the letter of its features but not their spirit. You know that feeling when you get a pair of headphones and the "integrated playback controls" are a single button that recognizes various sequences of short and long presses? Or a camera that advertises 240 FPS but it turns out that it records at 30 FPS and then inserts seven extra copies of each frame? This, by contrast, is a good product. A maximum viable product, if you will, rather than a minimum viable product. I'm very happy with it. Here are some details that you may be wondering about. First, the clamp tension securely holds a phone without crushing it in a death grip. As shown in the photos, a phone can be placed in two positions: near the front of the clamp, and behind the second set of "teeth." This is useful if you have - here's detail two - a phone with a thick battery case. The first position holds a phone of average thickness perfectly, and a very thick phone very passably. If you want more peace of mind, though, you can move the phone a bit rearwards so that its front is held by the first position's rear teeth. Those teeth may cover a tiny portion of the phone's screen (given modern narrow bezels), but that's part of what guarantees their secure hold. Third, the ball joint connecting the clamp to the gooseneck is perfectly serviceable. It's easy to tighten and loosen, easy to adjust when loose, and firm enough when tight. If you have a really heavy phone, though - or if you put one phone off to one side in the first position and another toward the opposite side in the second, like I do, because I sometimes want a miniature dual-monitor setup - it tends to sag even when hand-tight. I can't fault it for this, because 1) that's not a reasonable load, 2) you can just let it sag and then adjust the gooseneck a bit higher to compensate, and 3) increasing the load capacity would need a whole new design, not a simple/obvious fix. Even though it's not a negative, it's a good detail to know about. Fourth, the gooseneck itself: if you're not trying to bend it, it won't bend. If you are trying to bend it, it will bend. Pretty much the perfect level of tension. Fifth, the base clamp: padded jaws that won't mar furniture, and the knob to open and close them is that entire plastic tube that extends out of the base, making it easy and comfortable to adjust. Sixth, the stability of the whole contraption: as good as can be. The gooseneck's rigidity means that very little wobble comes from the product itself. Mounting conditions are more important: mine is on my bed's headboard, which extends upward without extra support - that can wobble before I even attach anything to it. One solution is to mount it at the lowest point of the headboard, but my solution (see photos) is to adjust the gooseneck so that it rests against the wall with just a bit of tension. This cuts down any wobbling to virtually nothing. Note that I have a bit of plastic around the part that contacts the wall, to minimize wear on the wall as well as on the gooseneck's braided nylon. If you use your phone in a desktop stand, pick up your phone (yes, now) and hold it up where you wish it could be instead of on your desk. Those of you now muttering "but I want it on my desk" are all set. The rest of you would probably benefit from this gooseneck holder.
