Question: What does this device actually record onto - some sort of a memory card or flash drive? I'm looking for something that will record at least 6 hours.
Document: It also has a tripod mount, allowing it to be mounted to a variety of stands with a quarter inch thread. Uses micro SD, which is not my favorite memory card, but they are widely available so I cannot complain based on that opinion.Battery life absolutely sucks. Powered off it will drain a AA in less than a week, battery life while operational is at least 3 or 4 hours I would say. Plan on keeping a pack of AA batteries with it when you are using it.
This device is fool proof if you need something simple. I'm using it to record music  therapy sessions and I haven't hit a snag yet. You just have to press the big record button. The batteries have lasted about 15 hours now without having to be replaced. It's easy to get playback from the device, although the speakers are pretty quiet.
The only thing I find annoying about the device is its appetite for batteries, but I believe recording with the highest possible bitrate all the time probably has something to do with that. The Zoom H1 uses one AA battery, and will drain it in as little as 4 hours of use, however... IT'S ONE AA BATTERY... so, i'm presuming it shouldn't be that big of a deal to carry 1-2 with you if you planned on recording something extensive.
Transferring the digitized files to a computer is uneventful - the H1 looks like an external drive when you connect it to a USB port. A single AA battery lasts for at least 5 hours recording time. I did waste some batteries by forgetting to turn the H1 off, which is easy to do. You could spend hundreds of $$ to buy an A/D converter, and also tie up a computer to digitize. The H1 is cheaper, smaller and less complicated to use.
The college paper I work for ordered two H1s last month and I bought one for myself as well. I was looking for a smaller, lighter and simpler alternative to my H4n as an external audio source for our HD video capable DSLRs.This thing is totally made of cheap plastic, everything from the mic guard to the tripod mount to the battery and memory card doors. Its definitely not what I was expecting coming from the H4n (which is very solid). The H1 is CHEAP.
this sounds amazing, I used this to record a musical and i was just astonished at how clear the audio was! there was little, if any background hum/hiss. the 2gig micro SD comes with it and it was more than enough, 6 hours of WAV audio. more than happy
I did pop in an 8GB card rather than the 2GB card that comes with it. Some negative comments warned about the difficulty of trying to remove the card when downloading.I also purchased the accessories pack that comes with two vital items: a sturdy, but not bulky case, and the adapter to download files onto your computer. The foam ball wind screen is a little large to store in your pocket, and I'm not sure it completely blocks out a lot of the exterior noise.
I use the heck out of these things recording audio for our prison ministry. I have 2 and they both work well. They do eat batteries, the instructions say you can record 6 hours, I get about 3 so I change batteries each session. I use them with a lav mic from radio shack that cost about $35 each and they sound good, although they do pick up a lot of room noise (coughing and laughter.) All in all a great product for moderate use.
These were taken by just setting the recorder on the bench beside me.Durability:  The device is very small and will fit in your front shirt pocket. I put mine in a sunglasses case when I carry it around. This is because the the top portion of the unit is light weight plastic and looks like it might break if dropped onto concrete. I'm always paranoid about sitting this thing or carrying it loose in my backpack. This is reason I gave it four stars.
I'm a documentary filmmaker and this a great tool! I plug my Azden SMX-10 into it and records great! The device is small and compact and mounts directly onto my camera rig. I use it for recording sound from my shotgun mic, EVP sessions, and narrations. Cheap, easy, great sound! It is very very sensitive though. It's not good for holding and recording. You also need to buy a good windscreen! I recommend a furryhead.
Answer: It comes with a 2GB micro SD card which'll record 320kbps MP3's for just under 14 hours.If you just want to record lower quality sound it'll go for well over 34 hours; and as you can imagine if you buy a larger micro SD card you'll have much more space to play around with:e.g. with a 32GB card you could record a good 12 hours on the highest quality possible (which would be 24bit/96kHZ WAV).Trust this is helpful, I personally just record @ 320kbps, and it produces amazing sound.
