Would and will buy again. No problems with playing, good solid feel.. I haven't taped since he earIy1980s. Then used the best non metal TDK and Maxell had. I did do a careful listening on my refurbished Teac deck. Used Steely Dan song aja original CD. Sounds grrrrreeeeaaat! Compared this tape with Maxell type two? XII-S and Maxell type one UR. The Maxell type two was a clear winner. I used the correct Bias, I hope. The RTM C 90 wasn't disappointing and will cont. to use as long as tape shortages last. The Maxell UR was a bit better at mid range. The RTM handled the highs and lows very well. Actually was surprised at the tapes I tried in contrast to what I've been hearing. I really appreciate a good Type one tape as the RTMs. I will not pay the steep prices for a quality metal tape..now off to TDK land for a test. ## Frequently Bought Together - RTM C90 | Type One 90 Minute Blank Music Cassettes | Ideal for Audio Recording | Studio Quality | Pack of 3 Cassettes - QFX RETRO-39 Portable Shoebox USB to Cassette Tape Recorder, Analog Cassette Tape Deck with Built-in Microphone, 3.5" Bluetooth Speaker with FM Radio - Maxell UR 90 Normal Bias Blank Audio Recording Cassette Tape, Low Noise, 90 Minute Recording Time, 5 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/677992731-c90-type-one-90-minute-blank-music-cassettes-ideal-audio](https://www.desertcart.tn/products/677992731-c90-type-one-90-minute-blank-music-cassettes-ideal-audio) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-21*
