This is a great product, for an extremely low price. I was surprised at how well it worked when I initially tried it out. Sound quality is what you would expect from a tape player, it isn't stellar but it's nothing to complain about especially at this price. It has a headphone cable, so can be connected to a walkman, iPod, laptop, or mp3 device which is very convenient.My only issue with this item is that occasionally the tape player won't accept it, and will pop it back out, but after a few tries, it usually works. I'm not sure if this is a problem with my particular tape player as I have not tried it in any other, or whether it is a product flaw. However, it doesn't happen too often and isn't much of a hassle to pop back in once or twice.Overall, I would certainly recommend this as a cheap yet very effective way of playing your iPod or other device through your car stereo.
