Ordered a couple batches so far and I'm 100% satisfied with the quality and consistency. Custom lengths are accurate; no problems with tapes being too short. The quality of the tape itself is very good for Type I. I've been dubbing my copies off at 1x speed on a Nakamichi DR-3 (very good deck, but not some crazy expensive nonsense, I'm not rich...), and they sound great. If you give it alot of negative bias, it will get a totally acceptable top end response. I recommend cutting the lows a little bit during record b/c they will sound a bit boosted on playback, but this is more a Type I thing generally, not specific to this tape. Definitely NOT garbage "voice grade" tape, so rest assured you can get good music dubs on it.
