Great size, bag is too small if you have any accessories beyond the recorder itself so I had to return the case.I almost wish I returned the whole thing. The biggest drawback is lack of single channel monitoring. I used it all the time on my old DR60D.

I use this audio recorder along with my Blackmagic Pocket Cinema Camera. I've used high-end Sound Devices recorders and mixers, Zoom recorders, and the Tascam DR-60D and this recorder exceeded my expectations for the cost. Pros: - Surprisingly durable construction.

We've used this for several months now... Not ONE issue at all! Easy to use and works as expected. This is one amazing unit!!! Absolutely silent, perfect audio reproduction, and (as a portable unit) accommodates anything we throw at it! The internal mic's are fantastic, too!

I do a lot of field recording of sound effects and remote recording of concerts and such, and I just bought this as an upgrade to my DR40. All I can say is this thing is amazing!

No complaints about the audio quality. I use it in my radio reporting and video work and have never been anything but satisfied. Two design quibbles keep it from excellence. One, the 1/4 " screw used to mount the recorder to the bottom of your DSLR is not durable.

Excellent Audio Field Recorder. Love this device. Previously owned the TasCam DR-60DmkII. Upgraded due to the types of interviews I conduct. Works even better than the TasCam DR-60DmkII.

I've been using this recorder for nearly two years at my film school, and finally decided to purchase one of my own. It is a great recorder, capable of capturing very professional sound if enough practice and patience is performed in using it.

"Mobius Strip" wrote Nov 21, 2015 that the batteries are replaced by removing the entire front of the device, which then dangles by a piece of tape. Assuming that wasn't a misplaced review, it must have been a design flaw that has been fixed in the current design, since the current manufacturer...

I love that this can be mounted under the camera. Menus can be a bit difficult but it can really nice features and solid build.
