I bought this set in preparation for a canoe trip I did with a friend for their birthday. I am so glad and happy to say this bag was wonderful and so was the phone pouch.It was only a 3 hour, 5 mile trip in shallow river water but I was nervous and wanted to be prepared as I don’t have much experience or feel too comfortable in water. I wore my phone around my neck in the pouch under my life jacket and my friend who was in the canoe put her phone into the dry bag which we attached to a bar in the middle. Well, the worst thing happened and we wound up separated with her solo drifting down the river in the canoe and I ended up having to walk through the woods to the nearest road. My phone was fully dry and functional from being in the pouch and I was able to alert people to my location so I’d be safe. My friend was also able to retrieve her phone which was completely safe and dry in the bag and we were able to confirm each other’s safety and get help.Her phone in the dry bag was also completely fine after we capsized twice.Absolutely the best money I spent and I am so thankful I had the foresight to purchase this set because it saved my friend and I from the worst possible outcome.This is a good deal, and the large case and the "hip-hugger" case work well. Bringing them to the beach or poolside, your stuff will stay dry. There is a tendency among some to think that the mobile phone case makes it OK to go swimming or snorkeling. You need to hope you have good luck. After a single use (i.e., sealing and unsealing it) when you open it up, the force of opening it up will likely rip off one of the small tabs that holds the plastic in place for a good seal. If you find it and put it back, great, but you really can't depend on this for more than keeping your iPhone dry and sand free while on the beach or, perhaps accidentally splashing it. If you lose it, well, don't even think about going in the water.The other two cases are reasonably made and the material seems durable. They worked well.I give it 4 stars only because of the iPhone case is troublesome and unreliable. The other components of this kit are very good and "5 star" worthy.I think you need to be sure you don’t fill too close to the top, because then some water will get in to the items close to the top. It was used to store my stuff at the beach and I took it all in the water with me so it wouldn’t get stolen. I didn’t test in strong waves, just floating on top.This is waterproof and works as advertised. The 5L was perfect for 2 of us just carrying snacks, 1 water bottle (husband carried his own) a light windbreaker, and a small towel while kayaking. Having the phone pouch was perfect for access to taking pictures. We love the 5L size for also visiting the pool on vacation carrying a few things & cell phones. If you want to carry larger or more items, skip to the 10L or larger. FYI: we also bought a 10L to carry more items while water sporting. Additionally, we already have a 30L for when others join us for water activities. My husband appreciated the waist bag vs. having the phone pouch around his neck. This is an excellent product.These bags have come in handy so many ways! The materials of all 3 bags are very thick, I believe they will be durable too. The bags are waterproof, very well and surely keep things dry during different activities in the water.Though I bought the 20L bag, which is, I believe, big enough to fit all I need during a trip including a towel, enough of clothes, sandals, camera, water bottle, and more. The lock is smooth enough to close and open.The waist bag is a perfect shelter for important small items like wallets, car keys, papers. It comes with a flexible strap that can be worn across the body which is perfect for both camping and kayaking.The phone pouch is another good addition that will certainly keep my phone dry.The lightweight is another big advantage of this whole package. I have found this to be a great product at a great price.Phone case is useless. Bag is worth it though, IMHO.The bag is good but for me to smallPurchased is in January- I took this Duo jetskiing with me multiple times and they worked amazing the lanyard attached to the phone holder is very strong and will not detach unless you detach it the pouch holds alot for its size and has 3 seperate squeeze seal to keep water out one last thing I have a note 10 and note 20 plus tested the floating ability AND IT WORKSSS I WILL DEFINETLY purchase for family highly recommended and affordablePrompt delivery, arrived ahead of schedule. Looks sturdy & durable. Tried once & all the bags worked fine with tight seal. Glad I picked up this set, happy with it.Feels like a good quality, strong. Lots of storage, flexible to use and easy to carry. Easily holds clothes, water bottles plus phones and hats. Would fit a light swim shirt too.Will be perfect for the snow & wet conditions (Haven’t had a chance to use it yet because of covid-19).Great product and fast delivery.I’ve used this product about 6 times and it has now split and will have to be thrown outIts very comfortable and handy. Reasonable price and exactly the same size as in details.
