First, the bag. It's a heaver, thicker plastic than I expected, based on reviews & the cautions. It's still plastic, still can puncture, but it's VERY sturdy. It took a beating so you needn't worry about these being cheap & flimsy.What I didn't get out of the seller's video nor on any of the reviews is that it floats. I mean - with your cell phone in it, the darn thing FLOATS!! I got that the bag floats when it's empty, but even with the phone in it, it floats!! YES! If you were to drop it in the water by mistake, you don't have to go diving to get it. I LOVED THIS! We do a lot of stuff around water and so wished for the ability to take pictures but didn't dare because I was afraid I'd either drop the phone and lose it or get it wet and ruin it. NO MORE WORRY!A review I read said the ribbon was flimsy, so I expected a thin ribbon such as what you'd put on a gift. No, this is fairly sturdy ribbon. It is a thicker ribbon-like lanyard that will hold. Like anything, it won't last forever, but it's replaceable and they held up to our day. I expected the clasp to come undone on the phone itself, and it did not. If anything, if you have younger kids, the ribbon is LONG. I wanted to tie it to make it shorter but my little one wasn't having it, she suffered through the length & eventually guess who carried it through most of the day? My greatest peeve with it was it got in the way of some of the photos. So did my fingers. It happens. Just be alert.I have a Samsung A20 phone. The children have different phones, smaller. Each bag held one phone perfectly, with room to spare. If I took the phone out of the case, I probably could have put 2 in 1 bag if I had to. As you can see in the photos, my case is rather thick and the bag allowed some extra room for some cash and a chapstick. In mine, I had taken a napkin and folded it. It was to be an indicator of water in the bag (Trust, but verify, right?). It also was used to protect my car key (not the fob, just the key) to keep it from poking a hole in the plastic. It did its job very well! Get this - my grand daughter even put her glasses in with her phone (thinner than mine) and it was PERFECT, both were protected well.Following the video instructions by the seller, we tested each bag thoroughly before we used them and each performed exceedingly well. When we went to the river, each bag again successfully kept out the water! You can turn the phone on/off, do pretty much anything you usually do right through it. The bag itself was thick enough to be a good protector for the screen & the phone, so crash, bang, boom, the phones did just fine.Caution - the blue nibs (I don't know how to call them) that close the bag a.) get stuck and b.) one fell out. Take a deep breath and look at it. You can put it back in if it's in the right direction, gently and firmly push them in. Make sure that the "teeth" inside are in the right spot. It's not flimsy, but it's not difficult, either. It only happened to us once when my grand daughter opened the bag at some point. It's not the kind of thing that should happen often, I wonder if she was experimenting with it, I honestly don't know. It didn't happen with anyone else. I fixed it in a breeze. You can see what I mean in my picture.I plan to follow the same steps for testing for leaks before each outing. Anything can happen. We are 2 adults, 2 young teen kids and this worked out so well, we bought a 2nd pack for our neighbors who do stuff like we do!Now the pictures. They aren't the greatest in terms of color. I included pictures here so you could see. We were in Florida, riding down the river, at a place called Blue Springs National Park, in inner tubes & floatie things that partially submerged us in the water. I purposefully included 2 shots that have a white blob - that white "blob" is a water droplet on the bag. My bust, I didn't see it, didn't wipe it off, but I still have my memory. I took 3 of those pictures while I was chest deep in the water floating down the river. Great memories, but the color isn't nearly as vivid as it could have been, but I guess a photo editor could restore the color if I really wanted. I actually expected that from someone else's review, so it's no disappointment.Also, I noticed that there's a blur around the edges of my subject. It turns out to be a pretty cool effect. You might like, you might not. It didn't seem to happen with all of them, so it is likely distortion caused by the way it was in the bag.One of the pictures is from my grand daughter's phone. She dove underwater and took a picture of a catfish that was on the riverbed. Keep in mind the water was over her head, she wasn't wearing her glasses and this isn't a half-bad photo for a kid. She used her finger to point to the fish.One word of caution, the seller's instructions say to keep your phone on. Well, that works to a degree. I found my phone had overheated so by about the 4th hour or so, I turned it off. No big deal, but it may be something you want to watch while you're using it. I turned it off while it was still INSIDE the bag as I never had to even open it. Protection to the very end.I will get another pack to keep if/when these go by the wayside.Hope this review helps you make a good, informed decision.
