It's as described, affordable for practice use.

Very good. Only one string was shorter than the others, which was not good. It arrived really quickly and was well packaged.

Interesting! I liked it a lot. Considering the price, it's quite advantageous. But I also have one additional point that prevents me from giving it 5 stars. For the price, I think it could have delivered a little more. I've already bought other brands that delivered the same quality for less money.
