[Sprint HTC EVO 4G LTE] fachadick:
I had an amazon gift card to use up, and we're planning a road trip to a waterpark so I decided to use the gift card to try and find a waterproof/water-resistant solution for my lte. I wasn't going swimming with these, but I did want to protect my phone from the the occasional dunk or splash, and I didn't trust a ziplock bag to do the job. I also didn't want to spend a lot (otherwise I would have gotten the overboard case).

I ended up ordering the following cases;

BestDealUSA Waterproof Underwater Pouch Dry Bag Pack Case Cover for Cell Phone PDA Blue - $2.96

Universal Waterproof Bag Case for Cell Phone / PDA, Blue - $0.01

Universal Waterproof Bag Case for Cell Phone / PDA, Black - $1.92

BestDealUSA Waterproof Underwater Pouch Dry Bag Pack Case Cover for Cell Phone PDA Blue

The plastic material seems strong on this case, and the seal seems like it would do a good job to keep the moisture out. The evo slides in and out easily, even with a tpu case, although it does it need to go in upside down if you want to take pictures - otherwise the camera is blocked by the opaque section of plastic, but this is not a big deal. There is a raised seal around the window of clear plastic (which takes up about 4/5ths of the phone screen) that makes pulling the unlock ring a little difficult, but not impossible. This is the biggest of the cases, with the most space around the phone. Screen responsiveness through the plastic is good, and the the window is clear, so its easy to see the phone screen. Lanyard runs through the width of the case, and seems very strong - I don't see it snapping or anything.

This one looks very similar to the higher priced overboard case and has great reviews. The areas surrounding the clear windows are puffy, as if it would allow the case to float. Unlike the other cases (which use a combination of two ziplock-type closure zips), this one has a plastic mechanical mechanism to squeeze and hold the opening shut like a vise. I don't know if I would trust this case to remain underwater for any length of time. It doesn't seem to seal as well as I would like, although the reviews all rave about how watertight it is. Having said that, the phone fits in this case perfectly with the tpu case, and even better without a case (upside down again), without being too snug, and the clear windows are exactly the size of the phone screen - only the capacitive buttons are hidden. Screen responsiveness through the plastic is good, and the the window is clear, so its easy to see the phone screen. The puffy areas around the clear screen also do a really good job of holding the phone in place, but makes it a bit difficult to press the power button. The lanyard that this case with end in what appears to be a thread that you loop through an opening in the case and seems like a good tug would snap it off.

Universal Waterproof Bag Case for Cell Phone / PDA, Black/Blue

I was only going to get the black one, but when I saw the blue one for a penny, I decided why not. These are identical cases, but one is black, and one is blue. These are the snuggest cases, and its a challenge to get the phone in, even without the tpu case. The plastic material the cases are made of is very tacky on the inside, so the phone tends to get stuck when you put it in or take it out. The plastic also seems thinner on these than the other cases, and the seals around the edge don't seem very reliable. Once the phone is in though, it's the most compact and pocketable of all of the cases. These cases do not have a clear window on both sides, so if you want to use the camera, then the phone screen will be covered by the translucent side of the case. It's not too bad, and the screen is still visible, but in bright situations, this could be an issue. Having said that, screen responsiveness is very good with these cases, most likely due to the thinness of the plastic. Lanyard goes through hole in the case and seems strong enough. These also come with an arm band that may fit you if you have the arms of a small child. They're really, really small.

Final thoughts - All of these would probably do a good job to keep water and moisture off of the phone (or even sand if you're going to the beach), and I think any of them would be fine to protect against accidental splashing. If I was going diving or swimming with my phone, I would probably shell out the extra cash for the overboard, or at least do some serious waterproof testing on these first. As it stands, I think I'll end up using the first case - Not too crazy about the blue, but I think it will do the best job of keeping the phone dry, and I won't need to worry about going down the log flume with it in my pocket or around my neck (like a tourist, lol).
