This part shipped quickly and I'm very happy with the quality. Easy to install on my flip flop hub. It has no click sound when wheel is spinning, which I like.

Reasonable price. Works reasonably well. No irritating noises so far. Works with a regular 4 prong freewheel tool. I like it.

Quiet, Reliable, Reasonably-Priced.

I needed to replace a worn-out, crunchy freewheel on my commuter. This one was reasonably priced and worked great out-of-the-box. There's almost no clicking sound when coasting, which is a little weird/pleasant. I commute everyday on it and it's still as smooth and quiet as when I installed it months ago. There are fancier, sealed-cartridge freewheels for those looking to buy the best on the market but for a no-frills bike commuter like myself that doesn't have a lot of cash to spend but still wants something decent and reliable, this is just perfect.
