Been a wet lube fan for years, as previous efforts with dry lube (White Lightening) resulted in a real blobby application and a nasty film that seemed to attract road and trail grime onto the drive train, so was always cleaning the stuff off and starting over. This however is a different experience altogether. Applies easily, cleanly, and the excess is easily wiped away. After a couple of months of summer use, the drive train seems to be less dirty than either my old wet lube, or the previous attempts to lube dry. I remain skeptical that this is an all-weather lube, but will see soon enough, and if it is, I'll even convert my off-road bikes!
I like a clean well lubed chain on my ultegra equipped bike since it improves the shifting performance. This lube performs well and can last for multiple 40 to 50 mile rides. I tried other lubes when my local bike shops quit carrying it but came back to Finish Line by buying on-line since the others didn't work as well. Thumbs up!
I use the teflon lube because it makes cleaning easier, is less messy, and picks up less road dirt. I clean the chain frequently. Don't try to toss it in your bike carrier for airline travel - mine was confiscated by TSA!
