Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
The outside of the bottle says "liquid bearings" so I took them at their word and just put small drops on the ends of all the moving posts in an antique wind up clock I have. Before the lubricant, the escape wheel (the one that you can see spin back and forth) worked for about 6 seconds and stopped. After the lubricant, the clock has been running and keeping good time for the last week. If I forget to wind it, it just slows down by a few minutes when it approaches the end (2-day wind).
If it stops running again, I'll have to clean it first, but this was a really quick and easy fix that didn't cost that much for a lifetime supply. I also put a few drops on a sleeve bearing in a HEPA filter motor that was occasionally binding (and squealing) and it runs smoothly again (about 5 days).
