Stylish case with a short lifetime.

The BookBook 5/5s case will look and feel lovely in your hand and pocket, but suffers a few important drawbacks that mean I cannot recommend it.

First off, the case impacts the iPhone's reception significantly. If you are in a very high signal area this might not be a problem, but it is constantly an issue for me even in downtown Chicago.

Secondly, the case is not built to have the phone repeatedly removed and replaced (which you must do to get decent signal for a phone call). Mine split down the inner edge at the base of the frame within months of buying it.

If $60 for three months of phone casing suits you, then by all means buy this product. Personally I don't believe in encouraging undertested products like this one, though - I imagine many 5 star ratings here are from owners after only a few weeks of usage, which makes this  high rating rather misleading. Buyers, be warned!

Gorgeous case...feels great in your hand, and love the thin front cover with the magnetic snaps. Just a really good looking and feeling cover.

The problems I had are the same that have been mentioned numerous times in other reviews. First and foremost, the plastic broke near the volume buttons after about 6 months. This is due to a combination of the volume buttons being very recessed and difficult to reach, and there not being much plastic in that area. The small piece is evidently easily breakable.

After that, it was only a matter of time before the magnet attached to that portion of the plastic broke off. Within a month or so after, the magnet on the right corner also came out. This left only the middle magnet.

All in all, the case lasted around 8 or 9 months. A very nice case aesthetically speaking, but I would have hoped for more longevity. Keep in mind that my tablet lives next to my bed and went on 2 plane trips in that time. I am not rough on it by any means...there just seems to be some design flaws.

I bought this because I loved the look of it.  I do get lots of compliments on the case.  It doesn't show any wear from being in my pocket and getting banged around next to keys once in a while.

The problems started when my phone fell out of my pocket while sitting.  It fell about 2 1/2 feet (really not that high) and created a split.  The wood split about 1 inch along the bottom corner.  The split slowing increased over the next couple days to about half the length of the phone and was starting to become loose on the phone.  This case relies on side to side tension to keep itself in place and with the split is was sinking fast.  It was starting to get close to the volume cut outs.  I tried super glue (no good) and finally gorilla glue fixed the issue.  Then to other side did the same thing without being dropped and this time when it split it went almost 2/3 of the way along the other side of the case (just shy of the power button cut out).  Time for more gorilla glue.  Two doses of gorilla glue in just over a month.  Not sure how much longer this will last.

The Good:
-It does fit tight to phone so it doesn't fall off like some of the cheap rubber cases that are not even the right size.
-All the ports and buttons are still easily accessible.
-Great looking and well made.  No pits or rough spots anywhere so looks really nice.
-It doesn't add bulk to the size of the phone.

The Bad:
-It only took one drop out of my pocket while sitting to crack it.
-Relies on tension to keep in place and is made out of a material prone to splitting under constant tension.
-Once even a small split occurs the integrity of case is compromised quickly.
-One big drop and the case could be ruined immediately

Overall:
The case is super light and eye catching but slightly fragile due to the wood.  I have mixed feelings on if I should get a replacement one or get a different kind of case.  If you are careful with this case, it might last a long time.  If you have kids who play on your phone, I am sure you will be replacing the case in a couple months.  There are other two piece wood style cases that don't rely on tension to keep it in place so I might try that kind next.

I liked this case a lot, but don't expect it to last more than about six months before degrading to the point that it poses a threat to your phone. At first it was just the fabric, which I didn't mind, but eventually the plastic begins to crack, and the wallet portion is more likely fling open. My advice would be to not carry it while the case is open. (This might be a no-brainer but I got into the habit and then cracked my screen when I dropped it after owning it about 7 months.)

Summary: I love this case. I would definitely buy another one. The wear and tear on this case is noticeable to me probably because I love how it looks so much that I'm saddened it is getting old, but I assume it's really not much different than any other cases I've had.

Pros:
-Gorgeous cover
-Real wood
-Feels very high quality
-Protects my phone (dropped it over 20 times without damage)

Possible pro:
-Gets attention and adulation from everyone that has seen it.

Cons:
-After about 4 months the casing around the volume buttons broke off (this is actually good as I didn't like that section anyways)
-after about 6 months a couple of strips of wood (about 2 mm wide and 1/2 an inch long) came off of the area around the camera and back

This case was sleek and slim and it fit nicely in my hand, unfortunately it broke after a couple months of use.

This is an attractive case for minimalists. It is a very slim case adding almost no bulk to the phone. The beautiful antenna band of the iPhone shows through in places giving this case a sort of lingerie appeal. The included screen protectors are also very good products. Where this case lacks is durability. Within the first few hours of iPhone ownership, my girlfriend got out of my car forgetting my brand new phone on her lap... iPhone 4 across the parking lot. My phone did not suffer a scratch (thank god!), but when I picked up the case, the protection for the top left corner of the phone was hanging by a thread.

Now my phone is unprotected from the (-) volume button all the way up around the band to the sleep button. I won't be paying $25 dollars for another one-use disposable case. Good try Sonix, but this case is too brittle.

I will now be ordering (and waiting a long time) for an Incipio Feather or Dermashot.

Case fit well and looks really good.  I liked how thin and light weigh the case was.  However, after using the case for approx. 9 months, 3 of the corners have cracked off as well as the thin strip around the volume button.  I would caution anyone who used their phone much against this case.  It's a great idea to make the case thin and minimal, however it doesn't seem to hold up too well.

Good case--lasted around 2.5 years and just now started to delaminate and break apart. Good looking and protects the screen well--I have received many compliments on its look. I have the cognac color, and it has worn well.

I really like this case.  It is lightweight, protective, soft on the inside, not too hard on the outside, has a convenient clip for hanging the case on a belt loop, and even includes a microfiber cloth for cleaning your glasses.  I have purchased three of these cases for myself and two for my wife.  The only negative is that they last only about a year or two, after which the leatherette zipper pull breaks off and the leatherette clip attachment tears at the stitching.  I usually replace the zipper pull with a metal split ring until clip attachment goes.  Would highly recommend with the understanding that it will not last forever.

Super classy case although it does not look that sturdy it will probably need to be replaced in a couple of months due to leather wearing off.

Nice case. Belt clip breaks off in about 6 months. However ,still a good price point

Wife loves this case. Doesn't add a lot of bulk but gives the phone some protection. Good design, sharp looking.

**Updated after a couple of months of use - the white starts to turn pink, as if either the color is fading out or the pink is wearing through. It looks terrible. We just replaced it after only a couple months of use.

Great slim case.

This is not a durable case so don't buy it if you're looking for something that will last you through dozens and dozens of drops. The case is not flexible enough survive for long, as ive had to buy  replacements a fews time in the past couple of years.

Beautiful case, but doesn't last long. Plastic edges began crumbling and breaking off.
