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!

5 November 2014

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.

Seems to work fine. Haven't used it enough to give a full review.

18 January 2017

Yeah, folks mention it can be noisy (somewhat) but for the price you get a really useful device, built in phantom power, flexible inputs, design works well under DSLR but have also used as a field mixer plugged into a broadcast level camera - though the connection is unbalanced.

Image what something like this would have cost 10 years ago. Remarkably intuitive, and a great backup unit for audio capture without breaking the bank.

31 October 2016

I bought this to replace my Tascam DR-40D and I'm immensely glad I did. I'm often operating a one-man crew and having the ability to mount this straight to the camera makes this worth the price alone.

21 September 2016

Took a little time to learn how to configure it. Internal mics work on channels 3 and 4.

23 April 2016

In order to get the best spec out of this unit is recommended to read reference manual. A lot of the negative feedback has been from people trying to exceed unit ability. Works great, awesome price. For this price point is the best out there.

30 March 2016

A little time spent to learn all the features, but works great, very good quality recording. I set the gains to High+ to get enough volume, but that may be the microphones that I'm currently using also.

26 August 2015

This is a great device. Works wonderful, I only wish the door to access batteries and the door to access the storage card were not the same door. A little funky to open and close.
