DSEAPLI4MIB 001 Endurance Waterproof Case for iPhone 4/4s - 1 Pack - Carrying Case - Retail Packaging - Midnight Black

I researched for a few weeks before I made a decision on this case. I'd search other models, some much more expensive. I decided on this one based on positive reviews and a video or two I'd seen taken from within the case. I got the case in and started my series of tests including:I started off with paper towels folded up and placed inside while dunking into the sink and holding for a couple of minutes. The paper towel remained dry.I then moved on to the neighborhood pool. After several occasions of being used down to about 5 feet, by my AND my children, no leaks, and excellent photos and video!This last weekend was the final "test" before taking it to the Cayman's. I took it SCUBA diving in a local lake down to around 30 feet. Completely dry after 2 days of diving! Snapped about 300 photos and some video!!!I can't say enough nice things about this case. The screen can be a little tricky to use at depth, but if you're in your camera app, it's a snap to use the + volume button to snap pictures or start/stop video.I highly recommend this product if you're looking to take unlimited underwater/scuba photos and don't want to mess with the pricey scuba disposables!UPDATE 8-27-12--------------Just got back from doing some scuba diving around Little Cayman island with some bad results.Day 1: 90 foot dive, but at around 40-50 feet, the water pressure pressed and held in the main bottom button. The photo app still worked because I was already in it. At around 65 feet, the pressure pushed the power button until the phone turned off. I kept going down to around 90. Once I came back up, it looked like about a drop or two of water had infiltrated the case. Phone still worked without a problem. Date 1 note to self, stay in less than 50 foot of water if I want to maintain functionality.Day 2: Snorkeling with short dives to about 10-15 feet of depth. Phone/camera worked flawlessly. Phone was completely dry after about an hour of this activity.Day 3: 50 Foot dive (on purpose to keep camera/phone working). Button's malfunctioned earlier this time. Were they weakened from the first dive? A few minutes into this dive at about 45 feet, the case sprung a huge leak and soaked the phone.I'm back home now and still trying to revive it. My recommendation: Good for neighborhood pools and snorkeling. Not a good case to take down beyond 30 feet IMO!UPDATE 8-28-12--------------RIP my 4s :(

You will find most waterproof cases open length-wise (merging a front and a back piece). Obviously, a gasket is used to seal that seam and keep water out (a roughly 15" long seam for the circumference of the iPhone 4/4s). One simple observation from a non-engineer, but DriSuit's design loads from the bottom, which has a small removable section. This method makes for 5 inches of seam to seal. That's 1/3 the seam size and (given an equally effective gasket) 1/3 the potential for failure.The design, including the latches, is very well thought out and easy to use. It just works. The phone's sound, that is your voice to a caller and the caller's voice to you, is VERY clear. In fact, when asked, I've had people tell me that my voice sounds more clear to them while in the case. I know that sounds hoaky, but it's true.I know DriSuit heavily touts your ability to use the screen underwater. The screen is "squishy," because it has a layer of silicone embedded that keeps your touch capacitive while under the water. In practice, the ability to use the screen underwater is somewhat laughable. Sure, it's nice to have full camera functionality, but I'd say there are work-arounds, and the feature is marginal. In fact, the trade off is less functionality out of the water - the squishy screen is tricky to use.If one of your reasons for considering a waterproof case is to take photos/video in the water, you'll be very happy with this. Both are very clear, above and below the waterline.I've tried 3 different cheap pouches and the iOttie Waterproof Skin Case Cover Pouch for iPhone 4S, 4 Multi Purpose Protective Skin for Underwater Activity, Fishing, Ski, Snowboarding, Sand-proof, Dustproof, Bath Tub. The pouches made for cloudy photography. The skin was nice and very waterproof but rendered the phone barely usable as a phone (hinders audio). The skins are also disposable (after 2 uses each).I'm amazed at how few truly waterproof cases there are out there. Obviously, there are a million pouches and bags, but only a few actual workable cases.There also seems to be two price points, $30 and $60. The $30 case(s) have mixed reviews and potential cause for concern, especially when you're putting a $600 phone inside. The $60 units (Lifeproof, DriSuit, Otterbox, etc) have you wondering "why so costly?" I don't have the answer to that, but I can tell you that the DriSuit is well designed and manufactured. If you plan to be on or near the water for more than a day or two, this case is a great choice and worth the investment.
