Familiarity: I've used it several times
I started using Stans on my mountain bike 12 years ago. I just went tubeless on my road bike. I expected some fancy new product for road tires. Good old Stans was the recommended product and it worked perfectly. I just had a flat on my wheel barrow. Poured in some Stans and pumped it up, no problem. I guess if it works don't fix it.
