Great for Thru Axels
I mainly use this to grease the threads on my thru axles. So far seems to be working great. Only issue is the nozzle has to be cut when first used. Make sure you only cut a small amount off or you will have a ton of grease in your cap. Seems to be lasting a while and doesn't wash off easily which is good.

Good stuff
This compound works as advertised. One tube of this will probably be enough to last forever.

Works
In my experience, works well. This is also, of course, the correct type to be using on bicycle parts. (I've seen shops using the high-temp Cu type in the past.)
