I used it for a couple of years. When it works, it's great, but when it doesn't it's a frustrating, sticky mess. It just became more trouble than it was worth, at least to me. Having said that, a riding buddy did the whole Continental Divide last summer, from Canada to Mexico; there was one stretch where the group he was with had to ride through goatheads. Everyone on tubes spent a long day with the patch kit after everyone ran out of fresh tubes but his tubeless setup worked perfectly with many holes sealed instantly.
Most all of my weekend ride buddies ride tubeless, gravel and road, and it works for them and I'm OK with that.
