Query: Reliable Performance At Reasonable Cost

Like another reviewer, I buy these for church recording use. In our case, they are used for recording both the spoken word as well as music and singing. These cassettes have provided reliable service, and the extended length makes it possible for us to record a complete service without flipping the tape, a real benefit.Fidelity seems fairly good. We have had no problems with defective cassettes. The only burble was an incomplete shipment, but this seller (the recording store) promptly forwarded the missing tapes -- very satisfactory customer service.I think I can safely recommend this product and seller. Happy recording!
