Summary: I purchased this for an employee in our company and he uses it on a regular basis. It's very reliable and useful and provides excellent sound clarity on recordings. Lots of features and user-customizable settings. Easy to download files via USB. He uses it mainly for recording meetings and never has a problem hearing what everyone is saying on the recordings.
Started out as a good purchase, ended as a waste of good money

Summary: I purchased this to use for my class lectures and cannot believe I paid the money I did, for what turned out to be a waste after a year. For some reason the recorder stopped powering on with the batteries. Yes even after I recharged them and replaced the batteries with new rechargeable ones. I also went through the Olympus operating guide (I took time to print out) to troubleshoot the thing, and also tried updating the software, to which all attempts failed.
Summary: This is by far my favorite instrument. I use it everyday all day, and the files are easy to transfer to my computer for uploading to a website or sharing over the internet. It's got great sound and the size is just right.
Awesome recorder, but make sure all the parts are included!

Summary: I am pleased with the Olympus DM 420. The sound quality is great, and the device is easy for blind people to use. I also really appreciate its portability. I was able to purchase the device used, for about half the price it normally sells for. I have rarely had any trouble buying used or refurbished products; however, it was not made clear to me that this unit was to come without batteries or a USB cable.
Summary: I wrote a review of this device that was not very nice. THe device had to to be charged and the only way to charge it is to press a button while plugging in the USB (design flaw). Regardless, the company just called to ask me to delete my poor review. I was almost willing to do it until the representative became very condescending and asked if I received a manual with the product. SO here you go again, you have to hold the stop switch in in order to charge this device.
