Left me covered in blood and sealant

I had really high hopes for this sealant. It was my first time switching to tubeless, and all of my friends hyped tubeless up. Just to be safe, I carried a spare inner tube with me. Was on some gravel roads, about 60 miles from home, when I crashed pretty hard. I soldiered on, my arm covered in blood, when I hear the dreaded sound - "PSSSSSssssssSSSSSSsssssSSSS", sealant spewing everywhere. The cut was tiny, I spun the tire to try to get it to seal. The sealant stopped bubbling out and I thought I might be okay. Half a mile later, the tire was totally flat. I found myself on the side of a gravel road, in the middle of nowhere, cursing the "No Puncture Hassle" name of this product. With my bloodied arm, I removed the tire, to see there was still plenty of sealant remaining inside. Defeated, I threw in my spare tube, inflated it, and continued the slog home without issue. On this same ride, a friend of mine also got a puncture. He used Orange Seal Endurance sealant. After just a few seconds, his tire sealed up and he continued on without issue. I'll be switching. The way I see it, tubeless sealant deserves either one star, or 5 stars. Muc-Off failed me when I needed it most, and I don't think I'm going to give it a second chance. "But you should have tried a tire plug" ... the cut was so small, inserting a plug would have made the hole bigger than it was originally. I didn't have one to try, but the cut was within the size that Muc-Off advertises the sealant as being capable of sealing.

Why didn’t you add air bag into your tire?
