Great, but difficult to get started
First of all, the software wouldn't run on one of our computers, which was frustrating. I am not sure why, since it running XP. I installed it on a different computer and it ran fine.

It's definitely NOT user friendly. It DOES work, but it's not fun to figure out how. It's not exactly difficult, but it's just not so much fun. It's kind of drudge work. Still, it works just as it says it will.

The Lyric creator that it comes with is pretty easy to use, but you have to enter lyrics line by line (like the other reviewer said), so it takes some time and I'm not sure you'll want to enter more than a song or two at a time. But, it is a nice piece of software and it is definitely easier if you find the lyrics online and then just copy and paste (and correct where needed) rather than typing it yourself.

When it comes time to USE the iSing, you just turn it on and run it in karaoke mode. Press the voice button to remove most of the vocals, use the included microphone and sing away (although, if you have a better one, you might have more fun). The voice button is a great feature but if you have layers of vocals on your tracks, it won't remove all of them. This is good if they are background vocals, but it's less desirable if there is another track of lead vocals. This track will still be heard. Also, it seems as if the machine removes some of the instrumental track, too. Not much, but I think it's noticeable a bit.

We haven't tried record mode since we still need to get a SD card. I can see this would be easy to use, though. There is a record mode, so you would record on the card and you'd upload it to your computer and save the file as an mp3 (which you could then burn).

So, this product is first generation. And, I'm not sure it will be popular enough to cause the company to improve it for a second time. But, it's a pretty good product. I bought it for my 15 year old (an aspiring vocalist/songwriter). She loves to sing, but was put off by this system. I spent this morning figuring it out and putting a few songs on it, creating lyrics, etc., and trying it out. It IS a great thing, but the prep work required to use it as it's designed is NOT fun. It's not difficult, just not amazingly user friendly and not fun.

Using it, though, IS fun. It comes with clear instructions, a usb cable, microphone, line in and out audio cable and earbuds. If you plug it in to a speaker system (with the included audio cable) rather than the earbuds, you can have a great time taking turns and singing with others.

A little confusing at first, but a whole lot of fun
I got this for my daughter for the holidays. We struggled figuring out how to work it at first, so she let me try. I was really confused as to how to put the lyrics on the thing, but once I did everything was set. The bad thing is you have to insert a line of lyrics and match it with the time, but its pretty fast and easy once you figure it out. After all the lyrics are in, its pretty fun. My daughter is happy singing her own songs, unlike traditional kareoke where you have only the songs they choose.
