If I had the option of ranking the three questions on a 1-through-5 star basis rather than Yes/No, I might give "Is it a good value?" a 4. This stuff is pretty expensive. But it's still a good value because it works very well. I used this product in a chain-cleaning kit, and the results were a bit better than I expected. Even with no adjustment to the derailleur, which hasn't been recalibrated in years, the shifting is a lot smoother - so much so, that I'm now inspired to go ahead and take a crack at recalibrating the derailleur.

This stuff goes fast especially if you’re using it once a week like I do committing. One bottle lasts about a month using it conservatively. I really wish it came in larger batches for the price
