Waterproof and solid build

Very well made and sturdy, water proof is probably my favorite feature. Feel it's a bit over priced for such a small container, but over all a great quality item.

I got this for a friend and he loves it. Was a steal for how great it runs, and it has a few neat features to it, like the programmable shortcut button, and some cool widgets (it has a compass, among other things). Has a really solid feel and a high waterproof rating

Almost looks like Pelican built it. Other than the connector access port, it would be waterproof. It's well padded and holds my hard drive snugly. Well built, solid little box.

Purchased a bunch of this a year a go and they have survived so decided to buy some more taking advantage of the sale this are solid but if you need more protection go for the tough system they are more rugged and water tight

I got this case for peace of mind while taking my P4 out on the water while fishing. I loved the waterproof rating, that it had 4 clasps, and was made of what I thought was really tough plastic. Like other reviews mentioned the foam probably puts a little too much pressure gimbal and prop motors than I would like, but that was an easy fix with some scissors and a pocket knife. The organization was great, and I could carry all my (limited) drone gear easily in the case and had no problems with TSA or getting it into overhead airline bins.

The case would get 5 stars from me if I didn't have a latch break on while simply locking it down in place on my first excursion with it. On a boat. In pouring rain. In Alaska. With the failed latch, the case doesn't have enough of a seal for me to have confidence this case is still waterproof (had moisture on the interior foam after trying making due with 3 latches for the rest of the fishing day) , and not being able to trust it on the water or in rain pretty much kills my main use for it. Not sure if I got a bad batch of latches on my case, but if you're getting this case to keep your drone dry like I did, you don't want to get stuck out in the elements with a chance of ruining your drone.

I have been looking for a waterproof case like this since owning my previous Iphone.
This heavy duty case is much like my Otterbox.
Multiple layers of protection. You have the hard case shell, and the cover includes a clear screen protector likecover to fully seal in your phone. It locks into the other case, and if desired can lock into the black outer holder that has the rotating clip.
Nice heavy duty materials.
This phone case came sealed in what looked like a waterproof pouch.
Great marketing.
Know that your phone will be safe with this high quality cover.
I received a discount on this product in exchange for my opinion on how it worked for me.

I work in landscaping and spend 10+ hours a day outside.  After dropping my nano a couple of times I figured it was time to find a suitable case for it.

The H2O case is very well built, solid design using thick plastic.  The controls work fine (the touch wheel control requires a tiny amount of pressure) and the case seals well against dust and debris.  The arm band works great and keeps the nano controls from accidentally being pressed.

The case might be a bit bulky for those wanting a case for general purpose.  But, for those that exercise or work outdoors I find the case is the right size as the added bulk makes the nano easier to hold and less likely to be dropped.

Cheap and water-resistant. Have it in my shower and I can listen to podcasts.

Bought these for my 6 year old and they are made very well. Construction is solid with nice seaming and form. Great fit and cushion for fall hiking!  Waterproof outside will be a plus!

If you're looking for a basic waterproof speaker, and you're not expecting Bose bass, this is the speaker for you.  Just make sure you keep the rubber port covers closed. :)

Pros:
Waterproof (keep those port covers closed!)
Loud
Well constructed
Comes with a small hanging strap
Has a built in mic for use as a speakerphone

Cons:
Loud, but sound at both ends of the frequency spectrum loses detail at higher volumes.  In english this means that you lose both bass and highs at high volumes.  To be expected with a speaker at this price point and size.
The included strap isn't large enough to fit most shower heads.

Important Notes:
In order to be waterproof, you have to keep the port covers closed.  If they aren't closed, it's not waterproof.
The speaker will float, but you'll get very little sound if water is sitting in the front speaker grille.  Turning the speaker over to drain the water from the speaker grill is all it takes to fix the problem.

Conclusion:  I purchased this speaker for one of my children to use with her iPad.  She loves it.  It's built like a tank, and can float in the bathtub.  I plan to purchase two more for my other kids.

Works great for my Android Maxx. I tested it out in as the package recommended before using it with my phone. It is VERY waterproof. I was able to submerge it underwater completely. Great for the beach or waterpark which is what I will be using it for.

This item is well built and holds water! Can't really ask for too much more.

I do a lot of kayaking and winter hiking, and needed a waterproof case that also had a battery so I could run the GPS all day. I've literally spent probably 18 months looking for and trying different cases, but they've all had serious problems. But with this case I finally found what I was looking for. I've been using it at least once a week for about four months for my trips and I've found it to be excellent.

The phone stays dry both in my dunk tests and with water splashing over it in the kayak for hours at a time. The design is clever and unlike other cases with gaskets and hinges I always feel my phone is safe in it. It takes some effort to remove the case but with a little practice it is no big deal. I am surprised how little extra bulk it adds considering it is waterproof (much less than the other case I tried).

Screen visibility is very good even in bright sunshine, and tactile-response is good -- some problems at the bottom edge but I hear they have fixed this in the latest version. I find sound quality in and out to be surprisngly normal -- no problems talking on the phone or hearing music/ringing. The ports are little hard to open with gloves on but they do keep the water out and allow access without removing the case. The plugs may look like they could break-off in pictures but the material is thicker and stronger than it appears.

As an added bonus, you really get two battery cases in one -- when you don't need the waterproof protection, remove the outer two covers and you get a nice slim and attractive battery-case with a bumper. I've found that really useful for times when I need battery but there was no water threat. Also, the ability to carry extra batteries is wonderful for multi-day trips with no access to outlets. I was expecting degradation in photo quality based on all the other waterproof cases I've tried, but so far I can't notice any. I'm guessing they use optic-quality plastic or glass (can't quite tell what it is).

Company support is top-notch as well. They are very responsive and professional. I highly recommend it all around.

Perfect size for what I needed them for. Very solid construction and definitely water tight. The latch holds very well and is still easy to open. These also two holes for small padlocks if needed. They will fit a smaller cell phone/smartphone. Any phone that roughly 2.6 inches wide or smaller will be fine. Anything over that and it will get stuck when you close the lid or just not fit at all. Great case though.

Very well built. I only wish that it came with rubber rings/grommets to go around the wire and make it water resistant. Right now it doesn't come with any, and if any water gets spilt on it, it will go on the inside, making it susceptible to damage or shorts. Other than that tho, works great.

Solid, durable, and a logical choice for the occasional use of a stand alone water bottle.

Waterproof and durable so far

No leaks and it's holding together fine after nearly 10 times wearing it.

I have not had the chance to test out if it's windproof yet.
