Summary: I've been using this for a while know and there's been no problems. I use it for spoken word not too much music. The Battery is terrible though, I tried another holder and several different batteries but still haven't got too much out of it. otherwise it works well.
Summary: I have had this model for about five years and use it daily in my work and absolutely love it. It has never let me down and the quality is extraordinary. I tried a whole slew of cheaper models prior to this but they just didn't cut it. I will always buy Marantz from now on.
Summary: I am in aggreement with Vivatone66's review of this recorder and I think the review is thorough and good. I would add that I use the Marantz CDR310 for guitar lessons. When I give a lesson, I record it and then burn the lesson to a CD-R.
Summary: The product discription is misleading. The recorder does not weigh 24 lbs. I'd estimate 3-4 lbs. You can pick it up in one hand. The first unit I purchased would record up to specs, but when I inserted a blank CD, it would only burn up to a minute or so then eject the CD.
