Durable & Reliable
I bought this to use while kayaking, to protect my phone from water exposure/damange and from accidentally falling into the water. It works perfectly for that! I hook the lanyard around something on my kayak (a bungee on my dashboard, or a loop on the seat adjuster), to keep the phone tethered to my kayak (so it doesn’t fall out).It does NOT float, inherently. But if you make sure it has enough air inside it before you allow it to close, then it CAN float. (That’s too tedious for me to remember each time I open/close it. So I treat this as if it will sink.)This is reliably waterproof! I didn’t realize how great that would be, but I’ve tested it a few times and now feel comfortable holding this under water and taking videos/photos. The underwater pictures turn out good (not amazingly excellent, but good enough).I don’t prefer to take pictures (above water) with this case on, because the material of the bag can make the pictures look less crips & clear. The first time I used this, yes the pics were pretty clear – I think because the material was brand new, unused, and super clean. But since then, the pics tend not to be crisp & clear – perhaps due to environmental residue? I have rinsed the outside of them after use, and it doesn’t really help; but I wonder if I used soap & water to clean the outside of it after each use would help… but I’m too lazy. Pics are more clear if you press the case against the phone, rather than having it gap in front of the camera lens.The magnets are magical! It quickly closes and strongly seals on it’s own. It could not get any easier! It’s not at all difficult to open it; but it definitely is not going to open on its own.Regarding challenges with these sorts of dry bags, I’m happy to report that:- It opens plenty wide for me to easily get my phone in & out.- While the material does “stick” a bit to my phone, it’s NOT so stuck that it’s difficult to get my phone out of this easily and quickly.I only use this for my phone. But I didn’t have my phone in there, it could hold my keys and ID just fine. But I’d worry that over time a key would puncture this.

Good size and durable!
Strong magnetic closure, durable plastic and big enough for key fobs and also keys.

I’ve tried all the waterproof phone cases and this is the best
I have to bring my phone surfing due to work reasons. I have tried all the waterproof phone cases and this one is the best. Most will work perfectly for 3 or 4 uses and then start letting a huge amount of water in. This one will work for more than that, and then eventually let a small amount of water in. Sadly still not perfect. But most modern phones can handle a bit of water. I don’t like the price, but the product itself is certainly a step above the competition.

Works very well! (Didn’t last as long as I’d like)
Edit: Bag finally failed. One of the magnets started rusting out and bulging. The bag now lets a small amount of water in sometimes. Just over 2 years isn’t a bad run but I did expect a bit more.The bag works very well and is super quick to use. Just make sure you don’t disturb the magnets too much during use. It will probably be ok regardless. The material quality is above average which it better be considering the price.

works as advertised
I was a little skeptical about the design, but it hasn’t leaked after 10 surf sessions. My old Aquapac has held up after years of use, the Fidlock was a little cheaper so i made the change.

Do not use scuba diving.
I purchased the mini case to keep the car key fob dry during scuba diving. It magnetically sealed, so I thought it would work fine. It failed on the first dive, depth of only 30-40 feet. Key fob was soaked. The description says waterproof, but does not give a depth rating, so beware. Because of the similar magnetic closure, I assumed it was comparable to the Gator brand (used and never failed), which is waterproof rated to 100 feet with a lifetime warranty, including contents.

Best case
I love this case. So easy to use, no clips or latches. Best of doesn’t leak!

Works just fine but not the colour I expected
Description is transparent white but none of the part was transparent, not very nice if you expect a see-through dry bag.

Tres souple et tres efficace

Works well and fits a DEXCOM receiver for G7Snug fit but it works with a little force

Ich habe mir die Hülle für mein Handy bestellt, bevor ich dieses Jahr Kajak fahren gegangen bin. vorher hatte ich immer billigere Exemplare bei welchen entweder der Verschluss nach einer Zeit den Geist aufgegeben hat, oder sie waren nicht zu 100% dicht. Der Magnetverschluss der Fidlock Hüllen ist ziemlich Idiotensicher und schnell zu benutzen wenn man das handy aus der Hülle nehmen muss. Die qualität ist alles in allem sehr gut.

The product is amazing, however you should note the opening is smaller than the bag itself so give thought to what you want to put in it. I had to return mine and get a bigger one because my phone would not fit into the opening. The return was a painful process. They carrier did not show up the day they said they would so I had to reschedule. I waited on hold for an hour and 20 minutes before my call was answered.
