Cassette *by J***S on 15 August 2025* Excellent case. And massive inlay for jotting down Ur. Tunes recorded tapes themselves are. Nice clear plastic with strong screws fixing and nice. Big labels. Great value as well for a complete mystery buy. I've never seen before 👌 ### ⭐⭐⭐⭐⭐ Excellent quality tape *by G***Z on 27 March 2024* RTMs ferric tapes are made to the same specifications as the old BASF LH, used by recording studios across the world. I’m absolutely delighted with the quality of these cassettes, zero dropouts and excellent frequency response, high output and good noise performance. In my tests with these cassettes, I’m using my Denon DRM 710, 3-head dual capstan machine that also benefits from Dolby HX Pro and adjustable bias. If you are buying RTM tape, you can be assured of a high-quality European made product.
