So far, I have been liking it. In the past, I have used a traditional lube that you would just wipe off after application, but this one actually is supposed to stay on. It creates a waxy coating around the chain which seems to be helping with friction.
I've been using this stuff for a couple years now and it works great! It lasts a long time and makes for very smooth shifting. It's super weird but the directions say that you don't need to wipe the chain after application and I've found that actually works really well, the chain just soaks it in over time and I've never had a problem with it attracting dirt. You want the lube to be dry before you start riding so applying after a ride is a really great option.

I've been using this chain lube for nearly 10 years after a recommendation from a riding buddy. I prefer wax since it stays cleaner, but most weren't super durable, whereas Squirt tends to last longer and I can go longer between applications. As with most lubes, I've had best results applying to a clean, degreased chain.
