KALIONE100 Pcs Recorder Rubber Belts 40-135mm Arcade Belt Cassette Tape Recorder Flat Cassette Tape Machine Rubber Belts, 50 Pcs 1mm Width and 50 Pcs 4mm Width, Cassette Recorder Repair Rubber Belts

Nice assortment of belts, excellent value for the money... they work great in the CD/DVD players and cassette players I've fixed so far, going to try other devices too. Highly recommended.

Had everything I needed to repair my tape deck. Beats paying 20+ for a pre-made kit. I did measure the old belts before order and found my deck only used these sizes before ordering.

Well, they are rubber of some sort and they are belts so I will give them 2 stars.Unfortunately these are a particularly bad and stiff rubber. Also, the manufacturing process is incredibly crude. Now, I didn't expect all that much from a bulk pack of belts but these are effectively unusable for a tape mechanism. In the best case, they have all sorts of machining irregularities on their sides. Worst case is the blister you see in one of the pictures.I took a "best case" belt and put it on a pioneer ct-w604rs to make sure the mechanism was functional. That is pretty much the only use scenario for these on a tape mech. They do work. Unfortunately the wow and flutter was averaging to around point 21 rms on the record deck.Knowing how bad these belts looked, I took a chance and purchased a much more expensive single belt. Installing that brought the wow and flutter down to an average of point 085 which is below manufacturer's spec.So yeah, these are really bad for anything that benefits from precision.

Worked perfect, repaired 4 tape decks. Had everything in this package needed to fix a tape deck from the 1970s (4 belts), 1980s (5belts), 1990 (4 belts), and the newest one from 2001 (3 belts). Now all 4 are up and running. I would recommend. Looks like good belts, very nice rubber replacements.

Worked well as replacement o ring on denon cd player. Size of o rings in package varies. Good item and value for money
