Review on 🔧 Sony CD Player Belts Set: 2 Drive Belts and 1 Door Belt for CDP-CX300, CDP-CX335, CDP-CX350, CDP-CX355, CDP-CX400, CDP-CX450, CDP-CX455, CDP-CX691 by Owen Phi

They are thinner than the original tapes which lasted almost 20 years. They may not last as long, but they work. You can use the tip of a plastic baby brush to tighten the straps as there isn't much room for your hands. Be sure to watch a few YouTube videos on replacing these straps before you begin, as some videos are better suited to specific steps than others. Replacing these belts takes a lot of time, but when you're done, the car will be like new. The only reason I gave 4 stars instead of 5 is because they are so thin I don't know how long they will last.
