An inexpensive if imperfect solution to taking your phone to the beach
927915
Took these to the beach for a couple of days, and kept our phones dry as advertised. Added bonus: kept the sand off of them as well. The lanyards themselves are a little cheap and didn't feel particularly durable, so we used those provided by our cruise ship instead. Touch screens do work through the plastic, though in bright sun, they're super reflective and thus not super useful. Image quality of the camera was not significantly reduced unless a drop of water got in the way. This was plenty good enough to snap some photos for Facebook and monitor the time and weather while sipping fruity drinks.

This is a nice cheap multi-purpose electronics holder. It expands to fit your device and is a good option if you like the flexibility of being able to use it eventually for a different GPS or other electronic device. The outside is stiff enough that it would take a good amount of pressure exerted on the case to damage any LCD screen inside. The sides and top are open, so this is not a good option if you're worried about collecting dust on a seldom-used device. The case expands to fit the device, and looks like it would comfortably fit devices that are up to 4.75 inches long and anywhere from 2.75 to 3.25 inches wide and .5 inches to .9 inches thick. The extra slot in front hardly opens and it would be hard to fit anything more than the shape and thickness of a few credit cards inside it. The "frustration-free packaging" is easy enough to work with that most people should be able to open it with just their hands. For the price and flexibility, it seems like a pretty good deal.

If you are looking for a cheap something to hold your phone, this will do. It fits right. A bit difficult to get the phone in and out. If you get a call, while the phone is in this while you are walking/running, you will likely miss that call. It looks cheap. I don't expect it to last very long. Moreover, attaching this with a smartphone to your arm feels weird and unbalanced. That must be why I don't see many people tying a smartphone to their arms.

Summary:

Pros:
 * very cheap
 * protects both front and back very effectively

Cons:
 * part of screen obscured by leather frame making typing difficult
 * frame interferes with "head" sensor

This leatherette flip case is compatible with the iPhone 4 series (4 and 4S). The phone slides into a frame; the front of the phone is completely covered by the flip cover when the case is closed giving quite good protection to the glass face. The cover is hinged at the top of the phone. When the cover flap is closed a small built-in magnet keeps the cover from opening by itself. The ringer switch and volume buttons are accessible while the cover is closed as is the data port at the bottom of the phone.  The cover flap and the back are padded giving a nice grip to the case. It would be hard to damage a phone while enclosed in this case.

Given that the flap is hinged at the top of the phone, there is a small hole cut in the top of the hinge to allow a headphone to be connected when the cover is closed. This proves awkward as when the cover flap is opened and closed the headphone jack can interfere with the cover. More of a problem is the frame around the front of the phone encroaches on the edges of the screen just enough to make parts of the screen hard to touch. For example, when the keyboard appears, some letters are hard to reach. I find it easier to take the phone out of the case when I need to type more than a few letters. The slot cut-out to allow the data cable to be attached is a bit small sometimes requiring jiggling the cable to seat it properly.

Normally, when you hold an iPhone to your head and talk into it like a regular phone, there is a sensor on the phone that detects this and disables the screen so that your cheek does not type on the screen while you talk into the phone. This case interferes with this sensor at times causing the screen to activate when you are talking. If you rarely hold your phone to your head to talk this will not be an issue.

In short, if you want a very protective case for a very low price and are willing to put up with some inconvenience, this is a good case for you.

This works well enough, but there are a few issues: it leaves your phone under the sun on the dash where it can become quite hot and may lose it when starting off uphill (I live in San Francisco where my phone has flown out of this cradle on uphill starts more than once).  It also makes it a touch more difficult to reach from behind the wheel.  I would recommend instead a phone holder that attaches to your A/C vents.  If that doesn't work for you, then this makes a useful if somewhat less effective alternative.

I ordered this when I lost an important rubber plug on another waterproof case I had for my Galaxy S3.

The device works as advertised, it is a waterproof case.

Pros: It can be thrown in the water, and used in a swimming pool. I tried it my pool and it didn't get wet.

Cons:  1) The front screen isn't made of a hard plastic, but rather a transparent rubber/plastic materials. It seems as if It could be punctured easily with a sharp fingernail.

  2) There is no access to the power or volume buttons on the side of the device, this is a big deal

  3) No audio: there isn't a speaker for sound to come out of the device, I understand that many would say why do you need sound when you're underwater, the reality is however, many people use these cases when they're out at the beach or at a pool, and constantly opening them to listen to a phone call, or adjust the volume, only increases the likelihood of the device getting exposed to water.

You need to use the metal plate and glue it to your phone's casing, otherwise it won't be strong enough to hold it in place in bumpy road.

Found this cradle looking for a way to have my HTC one propped up on a bedside table.  For the price, it does a solid job.  Simply plug your micro USB charger into the back and then slide your HTC One into the cradle and voila, you're charging the device upright.

The removable piece is a nice addition if you have your phone in a case.  I found my Otterbox to be a bit too bulky, and prefer to have the HTC in the cradle without a case.

Docking a star because of the tricky connection with the charging portion of the cradle.  It took some time to figure out how to insert the phone just right for a stable connection.

It protects the phone well, but very difficult to flip open the charging port. Loud humming sounds are sometimes a problem during calls but not too often. My wife got it for a beach vacation, was pleased with it and has kept it on the phone. It is inexpensive and good protection for the phone.

I bought this case because I spend a lot of time in the outdoors and often use my phone for photos, calls, GPS, etc when doing so.  Despite some shortcomings, it provides peace of mind when using my phone outdoors.  If it ends up keeping the phone protected, then it is worth it.

Things I liked:
- Not as bulky as I was expecting it to be.
- The case is easy to install and remove.
- The case works as advertised in keeping water out.  I tested it upon delivery by putting a paper towel on the inside, sealing it, then submerging in water for half an hour.  Afterwards there was no detectable moisture on the towel.
- The phone retains its full functionality despite the complete seal, including the fingerprint ID scan on the home button.  Additionally the lightning port is accessible for charging by undoing the conveniently placed clasp at the bottom.
- The camera still takes nice pictures as long as you are careful to wipe everything before installing the case

Things I didn't like:
-There is a distinct plastic feel when using the phone in the case.  The latest phones have a certain elegance to their design and how they feel in your hand, and this is completely lost when the case is on.  More so compared to other cases that do not cover the face.
- Sound quality is especially diminished by the case, both when playing music or videos and when making calls.  Additionally, because the case is completely sealed, the pressure changes inside the case transmit to your hand.  I found this to be annoying, but others may not.
- The directionality of the ringer switch is reversed by the case, working as a lever rather than as a switch extension.  Because of this, there is no external visual reference for when the phone is on silent or not, as is present when the phone is not in the case.
- The plastic covering the home button feels flimsy and as if it will be a failing point when frequently pushing the home button.

Does the trick, ridiculously inexpensive. Tested by putting my phone in it and trying to call it.  The double pouch (allowing a choice of blackout vs. one-sided transmission) is a good idea. Using my office card-key I verified the pouch does not block the magnetic resonance of that technology, Fits my fat Samsung Rugby Pro snugly.  A wider phone would not fit and a taller phone would not allow the pouch to velcro shut, which would not bother me the way I use it.  If velcro'd shut, the pouch would give a valuable bit of protection if dropped, the edges are seams with some cushion.  That thickness totally disables the control buttons, can't even adjust volume. So I often just carry the pouch in my pocket with the phone outside of the pouch but with the pouch between me and the phone.  That way I can adjust volume while listening to music/books.

Easy to install -- holds my iPhone 6S Plus securely; works well.  My only quibble is that when it's in the mount, the weight of the phone makes it tilt slightly forward from the top, which makes it a bit less than ideal if you're using the phone for GPS or Waze.  In a perfect world, the mount would be tight enough that you could angle the phone however you wanted and it would stay that way, but there's not a way to tighten it that I have found.  But it's not a huge issue; I can still see the phone reasonably well.  For the price, a very good product.

This little unit does what it was made to do.  I bought it for my iPhone 6 Plus.  I was concerned that the backrest might not be tall enough to provide good stability.  If it was designed specifically for this phone, I'd expect the backrest to be taller, but I've never felt that it wasn't secure and would fall out.  I use this mostly as a docking station/resting place for my iPhone. I like that the unit is soft and flexible, small and portable.  It is better than laying my phone down on a desk or table.  It is an inexpensive way to give the phone a home and a place to recharge, which also makes it easier to find.  Though I can use the phone while it is on the PhoneProp, if I push too hard the bottom lifts up a little, especially in the vertical position.  My preference is generally to pick up the phone when I use it.

QUICK SUMMARY:  Inexpensive monopod is great for alternative to paying top-dollar for an authentic GoPro monopod.

BACKGROUND:  I don't have a GoPro camera.  I used this monopod with my iPhone 5S instead.

WHAT I LIKE:

- Compared to a GoPro monopod, it's about one-fourth the cost!
- The phone attachment worked well with my iPhone inside its protective outercase
- Very flexible; you can position the camera in many positions to get the shot you want
- Very, very light - 5.6 ounces including the phone attachment
- The four segments of the telescopic extension collapse and expand easily
- For storage, it collapses into a little longer than a 12" ruler
- The locking mechanism worked very well, just like my set of aluminum hiking poles (twist/untwist each segment to lock/unlock)
- Made of strong, lightweight, black anodized aluminum (not plastic as another reviewer said)
- Versatile to use with a GoPro or regular digital camera
- The foam handle and lightweight design made it easy to grasp and hold steady with a surprisingly stable video result

WHAT COULD BE BETTER:

- The phone mount will keep your phone secure if you're not bumping it around, but the phone isn't clasped tightly enough to use this design somewhere that will cause the phone to be jostled (like, say, on personal watercraft)
- The foam on the phone clamp (on one side only) seems like it'll decompose or get overly compressed very quickly.  I wish they had used hard, non-slippable rubber instead (or, at the least, included a few spare foam pieces so if one falls off or gets torn, you can replace it easily).  A better design wouldn't have used foam at all.
-  If you have a remote control for your device, there's no place to insert it into the pole like a genuine GoPro monopod
-  The bottom of the monopod (by the foam handle, the place where it would rest of the floor if you were using it that way) is hard plastic, which would tend to slip easily on hard surfaces.  It also would do nothing to absorb any floor vibrations, either.  Here, I wish it had been constructed with a durable rubber piece to both absorb floor vibrations and to keep the monopod from accidentally slipping on a hard floor surface.

CONCLUSION:  This is a very affordable monopod that, for many uses, is just fine.  My minor quibbles aside, I can easily make use of this item to take selfies outdoors or indoors.  Recommended!  (Vendor supplied free item for unbiased product review).

Let's your phone out at any corner of the cheapy case

It does what I need it to: 1) it can fit my Samsung Galaxy S2 Skyrocket (with a silicone case), 2) its plastic allows me to interact with my phone's capacitive screen, and 3) its velcro strap holds securely to my arm.  That said, it's not perfect... it barely fits my phone both width- and length-wise (it's a struggle to get my phone in/out) and it covers my side buttons when the phone is completely inside the case.  But, for the price, these seem like minor issues.  I'm happy with it.

bought this for my iPhone 6. wanted something large enough that would hold the phone with a protective rubber case when I kayak. (did lots of damage when my phone fell when removing it from a case that was too small to include the rubber bumper). in that sense, it does the job.  reasonably easy phone insertion and removal.  can listen to music, etc, without difficulty, but the Apple OEM headset volume control, etc, will work  when plugged into the headset port roughly half the time.  Since the headsets work fine in my phone and all other functions work, it suggests that the pins in the port are not making good contact, or the wire from the port to the phone are defective.
