I’ve encountered a few of these harps and have seen three out of four break. I had a beginning harp student at a college who had limited funds and chose to get one of these Mid-East harps. Within three months the neck formed a crack that grew until it broke in two. She spent close to $400 on the harp and it only lasted a few months. The damage to the neck could easily cost as much to fix as the original cost of the harp. Another one formed a crack on the soundboard along the strings, and the third one began to crack down the center of the back of the body. The wood is low quality and inconsistent in strength.
There is also the issue of sound which is problematic because the soundboards are thick eliminating a lot of vibration, so that the sound of plucking the string is harsher and dies away more quickly than on a regular harp. Even if a person is willing to deal with lower sound quality – you do not have much guarantee how long your instrument will last. I have seen some last a few years at the most, but breakage in three months for $300+ dollars is a problem. You could rent a really great lever harp and possibly a small pedal harp for that same cost.
