I just wanted to start playing violin, as it was something I wanted to do as a child (now I'm over 30).
I wanted something cheap that could sound quite good, and after reading reviews it looked that this would do the job.
I bought it, and my teacher was quite surprised of it's sound despite it's price. After changing the strings for 1 set of pirastro tonica sound improved a lot more thatn it was before.
About the materials I can't tell much as I'm not an expert but it looks like the wood it is made off is quite cheap but sounds pretty good.
The knobs where the strings are attached at the top, at first I had to tune it once a week, but after a year or so I almost have not to tune it, it remains unmobile.
After 2 years, I'm still using it and I'm happy with it.
I just play it for fun and it is all I need.
It comes with a case to store it with straps to put on back, a bow and a rosin. The rosin I found it to be useless, at second day I thew the rosin to the bin.
I recommend buying a separate rosin+strings
