This is the only chain lube I use anymore, and I use it year-round. The caveat is that probably 23 of my 4000 or so miles each year are indoors, on a trainer. So, environmental conditions aren't very challenging, compared to those who ride in drydustywetmuddy conditions outside. The reason I love it for indoors is that it doesn't spatter off and throw black streaks all over my trainer or the mat beneath it, like several other chain lubes have done in the past (even after a wipe down upon every application). My chains have lasted much longer than expected, as confirmed by my handy-dandy chain tool, so I think this product does a fine job of extending chain life.
First off, I probably log 80% of my 3,000-3,500 annual miles indoors on a trainer, so I'm not exposing the drivetrain to really challenging weather (other than the 95% humidity of the pain cave in a longer session). In those admittedly benign conditions, I really like this product. Many others, namely ceramic-based lubes, have produced a black liquid splatter after some use that eventually makes its way off the cassette and chain onto my trainer and the surrounding area, which is no good. This stuff works and keeps the area clean, as far as I can tell.
This is my standard day-to-day lubricant. I re-apply it every week or so, depending on the weather. Keeps things quiet and slick. It's very low viscosity, so it can be a challenge to get hard to reach areas without making a huge mess.
I live in the Seattle, WA area and ride year around in all weather conditions, Dry Teflon lubricant works as advertised. I clean my chain about every 200 miles, (2 weeks of riding) then dry the chain and apply Dry Teflon lube. Quality product! You won't regret putting Dry Teflon lube on your bike chain.
Easy to dispense from the bottle and the lubrication goes on pretty easily. Just follow the instructions and wipe off any excess. Be sure to do this in an area where you don't mind staining or place cardboard on your work area. Otherwise I like this product. And remember, a little goes a long way.
My bike shop recommended this lube for our high humidity here in Houston. I use it on my road and mountain bikes. It seems to perform well and I have no plans to use another brand.
