Question: Looking for CD player that will start in middle of a track right where I left off & not return to track 1 when turned off. Don't know feature name?
Document: The Coby Cd player plays instantly even without stereo headphones. I love how the look and the feel has from today's cd players. The one big gripe I have is that when the batteries run low sometimes, it cuts itself off. That isn't right, but still, it's a good looking CD player to get for your money.
No radio, either, and it only runs on 2AA batteries, NO AC/DC LINE-IN JACK. So, remember. Don't plan to go jogging with this(who does that anymore, right?) just keep it still and you'll have no problems! If you're looking for a basic player this will certainly fill the bill. Anyway, there's much pricier ones out there with anti-skip and all that, if that's what you need.
I bought it because I needed a cheap CD player. Well I found it. If you like changing batteries after ~20 tracks this is your device. Don't breathe either while you're using because it will skip.These experiences happened day 1.Pros:NoneCons:Garbage
I ordered this mainly for price and the thought that my son would break it in a few months. I would like to point out its been two weeks and he hasnt broke it yet. But it skips easily upon moving, and the headphones you will definently want to upgrade, for the purpose i purchased this item for it works. But if your looking for a CD player to use for travel, you might have to go with a more high end product.
CD player constantly stops; in the package no  contact information, no label to return this itemI need help for exchange or return this CD player
This CD player did not work properly....used far too many batteries and skipped at the slightest jostle. My husband bought ot for vacation to listen to books but we had to return it because it was defective.
I remember when in 2005 I would use this CD Player when I came back from school, I would lay down in my bed and listen to Guns N Roses, Motley Crue and KISS, best times ever. I don't know anything about the quality of this since when I used it I was younger and did knew anything about CD Players...
This CD player is very inexpensive, but because it's very inexpensive, it's qualities are so-so. The biggest setback is the battery life. At the most is five six hours of music and then the screen shows a low battery signal. Another setback is the portability. Picking the CD player up will immediately interrupt the music flow. So much for portability. Another setback is the "skip" feature.
I recently purchased 7 for a classroom center. In the past I could get 1 to 2 years of service for an individual CD player in my classroom. These haven't held up for even 2 months. The main problem has been the locking mechanism on the lid. Very flimsy construction--the button to release the lid easily becomes jammed or off set and then it is impossible to keep the lid down. The price is excellent, but if it doesn't hold up it isn't worth it.
This product broke for us after 3 months of use, right after the limited warranty ran out. Still we just ordered another one because it works very well for our purposes and is so cheap at $12. Our 4-year old likes to listen to music or stories on CD as she falls asleep at night. She was able to use this CD player very easily on her own.
Answer: I believe it is called bookmark. I wouldn't buy this cd player. It is really cheap and uses batteries.  The seller I bought it from acknowledged it was cheap, but continues to carry it
