A case that really does as is promised.

This case actually does everything it promises; it does the most important thing which is to protect the phone and stay out of the way; but it also has a nice little stand which is very useful for sideways viewing!

This is a good sturdy case, with an inner soft rubber cushioning part wrapping the phone (except for the cutout for the camera/light and a cutout where the stand is, since the stand is a little thicker than the rest of the outer case) and extending above the face by a couple millimeters to protect against face-plants.  The outer hard plastic case grips fits and grips around the soft rubber very nicely; it's almost a little hard to remove because it fits to snugly. The feel is smooth without being too slippery.  The "kickstand" works well and is sturdy enough, and in landscape mode the unit is stable.  In normal "portrait" mode the unit wobbles a bit as the bottom is slightly curved, and of course that orientation won't work at all if a power cord is plugged in since the plug is on the bottom.  The stand is easy to open with a fingernail and snaps open and shut; those with fragile or unusable fingernails might have to improvise with something else (dime might work; penny is too thick).  There's enough room for slightly oversized microUSB connectors or audio connectors, and the power/volume buttons stick out far enough to be easy to press, but with enough resistance that they are not easy to press accidentally.  The case definitely ads some bulk to the phone which on the one hand make it feel very sturdy, but on the other hand it does make it harder to slide into tight pockets (that and the rubber sliding against cloth doesn't work very well).  But I do believe that my phone is well protected from most falls.

Note that I ordered the glow in the dark green unit, but the vendor was out so I asked him to send me the blue/green one (blue rubber, green plastic) instead, which I do like.  There's also no "odor" problem at all with this one (some users have reported the black rubber version have an odor problem; don't know if that's been resolved).

Case shopping by sight only is weird; close up photos make every aspect of every case seem magnified and magnificent, sometimes overblowing relatively modest products. When shopping I didn't like the idea of a two-piece case. This one comes assembled and there's no way the pieces will come unlocked when on the phone (nor when off), and the plastic keeps the case's sides rigid when on the phone. This case works well in various ways. Its large square button caps look good and are quick and easy to feel. The chiseled design grips well, though it could get a bit "edgy" (sorry) if holding the phone to talk for a long time. For the black model the back offers much more grip and anti-skid than metal or plastic parts and more than, say, the Otterbox Symmetry (which we have on another phone). Military brouhaha aside, the voids inside each corner (air pockets) make sense to me for shock absorption. And this case is slender! It works well even in a slender phone holster, with just enough friction to make any big-city heist attempts less likely. I suspect (hard to say) that the Otterbox Symmetry for sure, and Incipio NGP may offer a bit better protection, but this case seems to offer a lot. It's my go-to.

This is one case where the picture really does look like the product

This case is as close to perfection as I could hope for. It's a nice tight fit, the stand works a treat and it offers protection in all the right places. It's a little tricky to clip the lid on/off but once you get used to it it works a treat too. You can even fit the keyboard without taking the case off although you can't close the lid of the case the normal way and have to fold it back.

Pros:
+ Clever and well-designed
+ Sturdy and resilient with a resilient finish

Cons:
- Adds a slight bit of bulk and weight to an otherwise thin and lightweight device (but I'm not sticking a tablet in my pocket, so it's ok.)

I haven't tried any other cases, but hopefully I won't have to. This case seems like it will last for quite a while. No annoying snapping plastic tabs into one another or gingerly trying to snap flanges into device creases worrying about damaging the finish. The case was out of the packaging and on my HDX within 5 seconds -- no exaggeration. In that regard, the human factors get an A+. The origami fold is such a clever concept and creates some really nice line features on the cover. It takes some practice to commit the correct folding direction though. When you get it, you get it for good, though. The smooth, velvety inner materials ensure the screen and casing are well-protected. Good job on this one, Amazon! Worth the cost of two lattes over the other third-party cases, in my opinion.

The case looks and feels good, not too soft, nor hard.

Sturdy and large case.  It does just what the seller says it will.

I really like this case.  It is light but sturdy, flexible but firm, and I like the cheery color.  It shows no sign of wear after 3 weeks in and out of my purse, which is a testament in itself.  The double fold props it up at a great angle for desk viewing horizontally, or as a one-handed vertical grip.  The magnetic catch is very firm, keeping it tightly closed (in my purse, for example).  Delivery was prompt, product as advertised.  And a good bargain.

I've had this case for over 3 months and I have put it through extensive use in the past month. At first, I couldn't think of a single issue. However, I have found an interesting quirk in the past week or so. The lock for the Kindle is on the bottom right, and this case fits snug. When sliding it in every now and then, I noticed that the case actually clips the lock slider and effectively unlocks my Kindle. No biggie because after roughly 10 minutes of disuse, the Kindle auto locks. However, a few times after locking it, sliding it into the case, and then walking with it in my hand, I have opened it and noticed I am several chapters ahead of where I left off.

This is honestly my only gripe. It's minor, and once aware of it, you can avoid it 99% of the time. Just the same, it is a drawback that I never came across in the handful of reviews I read. I constantly get compliments on the case and feel it protects the Kindle very well--even in a backpack or messenger bag. I also brought it to the gym several times to kill time before a class. And the velcro, for anyone that might have concerns, shows no signs of wearing out.

I like the case as an alternative to silicone cases. This case is sufficiently 'tacky' to not readily slide out of a pocket or off a reasonably flat surface but, unlike silicone cases, is still easy to remove from a pocket.

I wanted, but was unable to find, one of the hard, transparent, 'clamshell' type cases for my Sony 545. This case, along with the screen protector that came with it make a good combination. It is true that the front buttons are in no way protected from moisture or dirt, which is the only real flaw in the design.

Like McB, I also thought (when I first got my previous one) that the connection for the belt clip was supposed to be forced through the small hole in the case. However, with a bit of thought and experimentation, it quickly became clear that the connector actually consists of two pieces that are screwed together. Simply unscrewing them (righty-tighty, lefty-loosey) reveals a small threaded projection that fits perfectly through the hole in the back of the case. Screwing them back together provides a safe, stable, and secure connection for the belt clip.

The fish keyfob that came with the products seems a bit strange and a physical non-sequitor. I guess it is just intended to 'sweeten' the pot as it has no connection to the other items. I'd just as soon have them not include it and give an option for a discounted 2nd screen protector or some sort of a wrist lanyard that fit the lanyard slot built into the 545.

Overall, I am happy with this product set.

Additional note (8/2012) I'm still using the same mp3 player and this case. The case has remained flexible and is easily removed for cleaning. It has successfully protected my player from modest impacts and continues to provide a better gripping surface than the player itself.

This case is very sturdy and durable for the price.

I had already purchased a Lowepro camera case to protect my Nuvi 760 - it works, but is awfully bulky.  I was intrigued by the Garmin case which I had not run across before and I took a chance on ordering it.  I'm glad I did, the case is one of the best I have ever seen of manufacturer-sold cases, most of which are pretty shabby.  The 760 slides nicely and firmly into the sleeve with the power switch and headphone jack accessible when closed.  When open, the screen is fully visible.

The flap holds securely with two magnets and there is a belt-loop on the back, though why, I don't know.

I am particularly pleased by the protection this case offers - the edges and corners are rigid and spaced out a bit from the Nuvi and the front and back are also well-protected.

Doesn't give a guarantee but this is the best case for the money.
