Query: Please do NOT buy this instrument

As a music teacher, I very strongly encourage you to avoid this instrument and others like it. Instruments not made by a respected manufacturer will not last and most repair shops will not touch them (and believe me, you WILL have problems). Save your hundred bucks and invest it in something good because you're going to end up buying another instrument a few months later. I have seen too many of these instruments and even if they don't physically fall apart right away (which many do because they are made of very low quality metals) they are very out of tune and require a lot of air, which is very FRUSTRATING to students. If you want your student to be successful and enthusiastic about playing, please purchase a quality instrument. Good used instruments can be found for as low as $200.
