Awkward fit, plastic casing seams broke
589676
The plastic casing of the Pengaz 30-pin head is thicker than apple original 30-pin USB cable so it did not sit snugly into the iPad and in fact felt unstable. I was afraid it would snap off the ipad. When it got caught against something else, the plastic casing of the Pengaz 30-pin end broke open along the casing's seams. I snapped it back shut. I would not buy this brand because I have 2 length types of the Pengaz 30-pin USB cable, and both of the casings are thick and does not sit well. I do like the flexible braided feel of the cable with their color options.

I picked this case because I liked the idea of the soft silicone/hard plastic combination. Having owned both styles of cases before, I thought a hybrid (to drop a highly over-used term) would be the best of both worlds. And it was...for a while.  The silicone part fit a bit loose around the iPhone 4, but when the plastic cover was snapped over top, everything fit snug. However, this seemed to but extra stress on the plastic cover. I have 2 different chargers for the phone and only one of them fit properly with this case on the phone. I had to remove the case to use the other one. This likely was a contributing factor to the cases' demise.  After about 5 months, I noticed a crack in the hard plastic near the connector port. I treated the case more gingerly from that point on, but sure enough about 5 months later, the entire bottom segment of the hard case snapped off. Since the silicone's bottom flap did not fit snuggly in the iPhone's connector port, the entire assembly was "loose" on the phone. I just replaced it with another hybrid case, but one with a slightly beefier design and build.  So, yes the case lasted almost a year, but considering it's price, I definitely got my money's worth. In fact, I could have bought 4 of these for what I paid for the "high-end" screen cover. But now that the Apex case is gone, it gave me the opportunity (excuse) to put a completely new look on my aging iPhone. So while you may be looking for a long term commitment from your life partner, it may not be the best way to go with your phone case.

Just to be clear, this review is for a genuine Speck case, not one of the pseudo cases reviewed by many.
I bought this case from the Apple store when i picked up my new 4s.  Felt good, fit hand well, and the rubber on the back made it easy and comfortable to hold.  In the six months or less that i've had this case, i may have (carefully) removed the Speck case 5 times.  Not dropped (I'm way past adolescent phone-dropping age).

Problems:  the plastic of the tiny piece that sits just below the screen and is the front of the opening for the charger broke off at one end (it's only about an inch long and very thin, but plastic with the black rubber); I superglued it back.  Then it broke in the middle; however, in both cases the rubber keeps it together.

I began to notice what i can only call stress cracks at all four corners and along the sides where the buttons are.

Apple says i have to send back to Speck (and their warranty excludes "normal wear and tear," whatever that is). Not sure if even worth the effort, even though the thing did cost $35.
So, not sure if i'll just live with it and get another case when this one finally dies, or go with something new.
In any case (no pun intended), it's comfortable, protects, but i wouldn't buy another.

Difficult to adjust and plastic key broke within the first adjustment. The waist doesn't adjust well if the waist is close to the measurement of the bust and hips. If you have odd measurements or unequal ones I suggest you buy a different one.

Might be Ok for some, but I returned it.  ULAK plastic is too hard and fit was incredibly tight.  Don't buy if  you expect to be removing the case with any frequency.

While installing the first case, the plastic snapped. The thin rubber strip at the bottom also didn't sit correctly. The new case arrived and the thin rubber strip still doesn't fit - it sits loosely outside of the hard case right below the button. I also noticed this problem on a friend's iphone otterbox. Seems to be a problem on all of them.

I love Sony Ericsson products, so I bought this with their reputation in mind. The sound quality and ease of use was great, but it was a very awkward fit for my ear. The ear peace broke off eventually from the awkward fit and strain. I can still superglue it back on and use it because I really liked the sound quality, but they could have designed it better.

I liked thIs case cuz I could set my note3 up on it and read recipes etc but theres a hard plastic shell inside the rubber casing and it fits so tight on the note3 phone that I had to literally pry it off my phone and while doing so it cracked. I returned the case because of that.  It's really bulky also which I didn't like.

I really wanted to like this iPhone case. Other reviewers compared the protection of this case to the protection Otterbox provides, which is why I was swayed to purchase this case. While I do not have experience with Otterbox, I can't immagine that it limits the iPhone's responsiveness the way this case does. The cover for the face is made of cheep hard plastic. I'm sure that it would take a few more impacts than the regular iPhone would be able to withstand, but the plastic makes the phone very difficult to use. You really have to press down and/or repeat your movements a few times. This is intolerable for me, and caused me to rip the front casing off of the phone in mere minutes.

The rest of the casing was satisfactory, as it seems rugged and well made. Unfortunately, using the rest of the case without the front covering makes for a rather loose fit. It is an annoyance but I still feel confident that it will stay on the phone. This loose fit does make working the power button a bit tricky. A few times the phone asked to power down when I was trying to put the port plugs back into the phone.

Speaking of the port plugs, it is the most valuable feature on the model. Quite frankly, this is why I wanted the case in the first place. Unfortunately the looseness means that the port plugs simply fall out.

The plastic sticky screen protector (that comes with most phones) is horrifically cheep. The top corner didn't stick even though I was very careful to clean my phone's screen and I didn't touch the screen protector. There was sticky residue from a removable tab left behind on the lower left corner of the screen protector. I plan on replacing it with a more expensive screen protector soon.

Overall, I'd recommend getting a Speck case instead of this case, especially if you can go without the front covering. If you need something to cover the front of your phone, spend a little extra and get an Otterbox.

Item arrived in transparent plastic packaging that appeared as though it fell a truck (several times)!  The case does fit the tablet well, however not a very tight fit.  The corners tend to pop off way too easy for my liking.  Returning mine.

Beautiful case. The plastic however was distorted- so when you put it on the phone the buttons that go over the volume and power won't work... I have tried to bend it to fit but it keeps going to back to original position. Disappointing because it was a very cute case.

This case is very cheap - can't believe the youtube videos I saw praising it. The fit and finish is awful - all sorts of bad seams in the plastic, etc. The parting line where the two pieces of the case come together is big and uneven, and the belt clip is garbage. It doesn't have a real hinge or metal spring - the only spring pressure it has is from the flex of the plastic. The mounting point to the rest of the case flexes more than the clip itself - this is going to wear out really quick. I'll be returning this for sure.

Really wanted to love this case. Also had the same problems as others with the actual plastic case part crumbling apart within days of use. The basic plastic snap on cases seem to be of much better quality.

Case was brittle and plastic layers separated and unglued putting phone in case.

I tried two sets of this item, and the headphones do not fit very well.  One of the earbuds even came loose from the plastic speaker part and got lodged in my ear, and was extremely difficult to get out.  The Swimbuds SPORT Waterproof headphones worked much better.

There does seem to be large build quality differences in both the jack in the iPod Shuffle, and the plug on the Waterfi headphones.  I tried two versions, and on one of the iPods, the plug on the headphones did not fit snuggly, and could "wiggle" in the jack, causing the audio to not transmit through the headphones very well.  The other version did not suffer as much from the "wiggle", but the jack still did not fit very well.

The plastic material of the earbuds is also not nearly as comfortable as the plastic on the Swimbuds SPORT headphones, and grow irritating more quickly, so I could not wear them as long.

I had this model for about a month and ended up returning it in favor of the Swimbuds customized iPod Shuffle and SPORT headphones, but I did try them concurrently.

Returned this item. Case charged well, is comfortable in the hand, and the speakers are nice, but the telescoping top broke off its tracks the second time I took the case off. The force required to get the case top to loosen is greater than what the telescoping arms can withstand and I pulled top right off the arms. Returning today and will be buying a different case. Disappointing.

Why can't they make cases that will fit as they should? The directions on the package did state to expect a super snug fit, at least at first. Fine. But there were other problems. The holes for the side toggle switches (2) are so tight it kept a constant pressure on, putting my cell phone into a confused state, going up and down the menu items. I trimmed the end of the plastic on both sides, and that seemed to take care of it. Next, even with the back case button snapped, the case hole for the cell phone earphone did not line up. That required cutting the area larger & wider. Finally, the bottom piece of the case must be removed in order to place the phone in the cradle charger. The case looks nice, and even with all my trimming, I'll still use it. But better planning on the company's part would have produced a much better product. Would I recommend buying one? No. If you do, plan to do some trimming. UPDATE 2/6/2010: The front of the case now has a tear on the front window, lower left. Thought I was careful with it, I think caused by the necessary removal from time to time to wipe it clean. Neoprene is NOT as sturdy as vinyl or leather.
