i love this harp! it has great quality and sound. i would suggest buying a chromatic tuner, unless you can tune by ear. it does come with a tuning key. i bought this harp for my 7 month old daughter. she is too young to play, but it is a nice showpiece for now. i enjoy learning to play it, as well. it is the perfect height for a small child, about 2 feet tall. my daughter can sit up on the bench now, so it is great for photos! the strings are durable, but i wouldn't recommend being too rough with them.
I really wanted to love this, but was disappointed. First of all the speakers had a very high pitched annoying hum every time a note was played or the game would talk. Also, the app kept crashing and it was quite annoying. So I will be returning it. Secondly, if you have an iPad - save your money and don't buy this. There are tons of piano game apps and lots of them are actually free. And they sound much better and work better than this did.
