I had been wanting an excuse to buy a Zoom recorder for a while - just to play around with and record my piano practice - and when my daughter needed to submit an audition recording for a band competition, I finally had my reason. I bought this because it was the only one in stock at the store - I had been debating between this one and the H2N. I know this gets used a lot by videographers who mount it to their cameras but I mainly wanted it for recording music practice sessions.
The pros - it was easy to use. I took it out of the box and basically was recording things in minutes. Getting the recordings off was as easy as plugging the USB cable into the computer and the device appeared as a hard drive that I could transfer files from. Sound quality was great - much better than what I could capture on my android phone and my daughter could get on her iphone.
The cons - it does not stand up by itself and if you try to hold it, there's so much rustling from your hand touching it that it ruins the recording. So you have to mount it on a tripod - I used one we had for our camera. Once its on the tripod, you can't access the buttons on the bottom of the unit next to the tripod mount. And when even on the tripod, this thing was so sensitive that it picked up the noise of me pressing the record and stop buttons so I had to crop that out using audio software on my computer. I used the auto-gain feature and it was a bit flakey - it did not do a great job of keeping up with the dynamics of the music and I could definitely hear noticeable swings in the gain level...I would recommend setting the gain level yourself vs. using the auto feature. Also, for my purposes, I really missed having a remote, which is the main reason I am upgrading to the H2N. The best place in the room to capture my piano is on a tripod placed at about the middle of the open side of the grand piano. But from there, I can't reach the record/stop without getting up from the bench. I suppose I could have just recorded the entire session and chopped it up later on the computer but I was trying to avoid dealing with huge audio files so I wanted to record the songs individually (and delete the bad takes as I went). The H1 does not have any way to control it remotely so I had to keep getting up and sitting down and of course it captured all that noise of my walking around which then had to be edited out later.
So I have returned this and am planning to get the H2N with the optional accessory pack that includes the remote. It's a bit more expensive but I think it will give me more versatility in the future -- the H2N can also record in surround so it is better for recording interviews or work meetings at a conference table. The H1 was fine and if you're just looking for an easy to use recorder that has good quality sound, I would recommend it. But to me, if I'm already spending $100, I'd rather spend a little more and have something that does everything I want.
