Bought these because I fancied a set & didn't want to spend much on them.
They seem to be well enough put together, though the finish could be better, the paint isn't great in places & the metal frames aren't the best, but to be fair, at the price I didn't expect any different.
They sound pretty good to me & as all I wanted was something to play about with, they fit the bill well.
Even with my limited experience, I know they aren't good enough quality for any sort of performance use, but to just play about with at home, they are fine. I'm happy with them.
