I purchased a Fox C60 and a EQ Professional C-90, and both have virtually the same performance, which is in line with a Maxell UR90. I only deducted one star from the quality rating because the cassette case doesn't hold the cassette shell tightly, which makes the cassette rattle inside, which isn't great. Apart from that, you're getting a solid Type I tape, with all the pros and cons of that type of tape.
