The unit is really tiny 
How is the unit?
I've had it around 3 months. I went to adjust the sound. It wouldn't work. Than I pushed really hard and the sound button imploded. I've had Apple Nano 2nd generation for over 2 years never a problem. I only bought this because I was bored. Price is cheap but if they only last 3 months the value is low.I'll try to warranty it but they'll probably blame on misuse.+++++++++++++++++++++++++++++++++++++++++++With a little threatening, they replaced it. So we'll give them credit for standing behind the warranty.  I have it sitting around because I just don't like the short battery life. My 4 year old Nano 2 goes for 12-15 hours compared to the 6-7 hours of this unit and I got tired of it always running out of batteries on me.+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++I'm very satisfied with this unit with one exception. I only get approximately 7 hours of listening time. This is leaving the unit on at a fairly high volume and doing nothing more than listening to books. I subtracted 2 stars because battery life is important to me and I've already run out a few times.I'm using it for Audible exclusively. I had a Ipod Nano 2nd generation and prefer the Sandisk Clip+ unit. This review is for Audible Users, others probably won't be interested in it. I was looking through the reviews and couldn't find a review that would describe the interaction of this unit with Audible Useage.1. Very small and compact- The unit is really tiny. All I want to do is listen to books. The screen is small enough to see easily but doesn't take up space so the buttons are larger.2. Great Sound-This unit sounds as good or better than my Ipod.3. Simple Navigation buttons-Took less than 5 minutes to learn.4. On off button which I use as Pause too. It is well located to the top directly over where the headset plugs in, I can find it by feel and don't need to see it. So it is convenient to find an use. When you turn off the book while running it comes back on at the same point still running. The time to turn on and start playing the book is less than 5 seconds. I've found that this feature is key to my enjoyment of using the unit with Audible. No fumbling through the other buttons to find pause.5. Convenient Lock mechanism, which I never use, just push the home button for 5 seconds. No cumbersome hard to find slide mechanisms. Where this unit blows away the Ipod units is that there is no touch sensitive wheel. Everything is push button. Without that sensitive wheel, I've never had to lock the unit. I had an Ipod which used the wheel which is sensitive so I always had to lock it. Big pain in the neck.7.Sound controls are on the side, again push button and stiff enough not to trigger by accident. I prefer this to the ipod system.8. It organizes each book into it's own separate folder so it's an extra click but your books are organized together9. When part 1 of a book ends it automatically go to the next part.But won't open a new book. This is advantageous because if you fall asleep with Audible running than it runs to the end of the part of the book you are on, than the next part (if you aren't on the last part) and than it goes to sleep. This can reduce battery drain.IE listen before going to bed.10. Uses the standard Mini USB connector (the one that's bigger) so you can charge and Sync with the standard one used on many devices. I just bought 2Technocel MV9MCDUO-SP OEM Sprint Dual USB Port Car Charger - Blackalong with 2Dual Micro USB / Mini USB Splitter Cable - Charge up two Devices (One Micro and One Mini USB) Once From a Single USB Port - Ideal for mp3 players, Digital Cameras, Smartphones (Android, BlackBerry, HTC, Samsung), GPS, and More. This gives me 2 micro USB and 1 Mini USB in my Autos. With 1 of the Micro USB being rapid charge. I love devices with standard Micro USB connection. By the way I have aDMMR: Dual mini USB and Micro USB to USB Sync and Charge Cable (Retractable)at my office and it charged and transferred data flawlessly with this unit.I have a mini usb connection at home that I use for my Card Reader also transferred data and charged it.  Hurray. It's standard Micro USB.12. Fast Forward and Rewind are as good if not better than the Ipod and convenient. Actually the Forward and reverse start slowly, than speed up the more time the button is held. This is advantageous because it allows for both slight f forward/Reverse and extreme f forward/reverse14.Expandable Memory using Micro SDHC. It was just so inexpensive I bought a 8gb MicroSDHC on Amazon for $6.00+ delivered8GB Sandisk MicroSDHC Memory Cardthis one is class 4 don't buy the class 2 might be too slow. With how cheap memory is it's better to buy the 4gb unit and upgrade instead of the 8gb unit. 4 gb does hold alot of books.15. Convenient Eject system from computer- I kept looking for the eject on my Windows Machine to disconnect. Finally I went to the manual. Turns out that as long as you aren't synchronizing you just pull the Unit out with no damage. Very convenient.15. You can listen to it while it's charging.The glitches:1. Battery life. Audible Playback only at fairly high volume using headphones. I only got around 7 hours. my Ipod Nano gets 14 hours. I had to take 2 stars off because that would be a deal breaker for many.2. For Audible can only use the Audible Manager.Remember Audible books are DRM Protected so you need the Audible Manager to decrypt and put on the Clip+3. Their is no way to organize the order of the books. It goes in Alphabetical Order (If I'm wrong please tell me how to do it in comments.4. Itunes tried to take over so I had to remove ITunes but I think that there is a setting or way that I could disableItunes from turning on automatically. Also my original default was through Itunes. Just be aware there may be issues withItunes and Audible Manager on your machine. Probably you can get around it.5. The books are grouped by Books. So if you are in part 1 of a book it'll play part 2 but won't go to the next book.Since it doesnt' go automatically. You have to stop and fiddle with it. This could be inconvenient for example if you are driving. Unfortunately once the book is organized on the machine their is no way to change the order. I have some books where it decided to put the Part 2 at the top and part 1 below. I tried accessing the drive in MTP mode which turns it into a hard drive. In Mtp Mode it showed as in order. So there was no way to fix a problem that doesn't exist when accessing the unit as a hard drive. To find the Mtp and MSC mode it's simple Press the home button&lt;Settings&lt;System Settings&lt;USB Mode&lt; For loading books Audible manager will only recognize in MSC Mode.6. I'd prefer that it used a Micro USB connector which is used on most newer phones.7. Controls are very small. I have to hold it in front of me to use all the buttons except the on off and volume button.8. When Fast rewinding or forward my Ipod used to allow me to hear the words so it was easier to find the spot. This is totally silent.9. If I turn unit off and than back on sometimes it will resume at the beginning of the chapter that I was on. But I had the same problem with my IPOD. So I don't believe it's a Clip+ specific problem.If you like this review please rate it as helpful. When I was deciding whether to purchase this unit, I had trouble finding anything about the compatibility with Audible
