I'm fairly happy with them. They feel good, and have a nice sound although a bit on the bright side. Compared to the Harley Benton valuestrings, there is no doubt that these are a better quality. But I don't quite see 3 times the quality for 3 times the price. On the other hand, they're not that much cheaper than Earnie Balls, and they don't exactly reach the quality and sound of those either. All in all, the Dean Markley are pretty good, they just don't reach beyond the OK-rating that I would expect for the price.
