Sonically and feature-wise, this is a decent recorder. In fact, it appears to be the only one on the market that isn't ruined by some blunder regarding dual recording (recording a second pair of tracks at a lower level, to as backup against clipping).

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! It is only a tiny bit bigger than the DR40, and designed to either mount to a camera or hang from your shoulder with a...

I was happy to find out that this small device allows for great sound. It is perfect for using with your video camera when looking for the best recording. It is easy to use after setting up the menu and following directions.

This is a really well thought out audio recorder for video shoots. Physically, you can mount it right under your camcorder so all the controls are right there. The DR070D feeds mic audio and a sync beep to your camcorder so sound/picture synchronization is a snap.

After using this as a rental on a corporate shoot, and being pleased with it, I bought this to use with my Panasonic GH4 camera, which I started using to shoot corporate videos. The internal audio on the GH4 wasn't bad but was a bit noisy. The DR-70D is such a huge improvement. Low noise.

I do a good amount of DSLR shooting and this is the exactly interface I needed. A huge step up from my old H4N. More control, better quality, better build quality. Great features, really brought my audio recording to a new level.The slight draw back was the manual explanation.

This recorder does the job ok but it's a little cumbersome. I love the form factor but you have to get used to operate it. The settings are not too intuitive so have the manual near when you're going to use it. Also keep an extra set of batteries because they don't last too much.
