TEANTECH 100 Pcs Recorder Rubber Belts - Cassette Recorder Repair Maintenance Mix Flat Cassette Tape Machine Rubber Belts 40-135 MM, 50 PCs 1 MM Width and 50 PCs 4 MM Width

Decent belts, you do have a many to choose from, but there are a lot of the same size and thickness, they work for a lot of different repairs, however a few variations of different size and thickness would have been better, unless you're going to use a lot of the same size belts. They're also not really heavy duty, most for like cassette or micro-cassette repairs, or smaller VHS components, not going to work well on record players and motors that use a lot of torque.

Replaced bad belts, made tape deck usable again. Large variety of sizes.

I only needed 2 belts but this package was less than half of buying just the 2 belt and they work great.

Just what I needed to restore my Radio Shack portable cassette recorder to operation. I found all three belts that I needed in this assortment. Fast forward and rewind will not operate correctly in this tape recorder if the FF and RW belt does not have tension in it; the player uses this tension to engage the common drive sprocket for these operational modes. The belts seem to be of good quality and have adequate stretch.

To buy the exact size I needed was difficult. So I took the shotgun approach and bought this big bag of assorted sizes. It had the exact ones I needed. I don’t know how long they will last but they worked perfectly.
