Used Stan's for protection against the tough thorns of India. Need to add more fluid every couple of months (riding on a 2 times weekly basis, with roughly 5 punctures per ride). loses a bit of potency with extreme heat (40 deg C) and light.
Stan's is the only reason it's possible to ride in India or other thorny places. Nothing else comes even close

Lighter weight and less flats, lets you run with less pressure to grip the ground tight. What's not to like?

I am using this kit with DT Swiss TK 7.1 rims on my 29er. On these rims, it is possible to seat the bead in just a few minutes with a floor pump. I was impressed to find that I experience no noticeable air loss between rides. In fact, the tubes on my previous setup would lose more pressure over time. On my rigid mountain bike, I am enjoying the lower pressures that running tubeless allows.

Inflated easy and rides good. But the stan's sealant won't seal up, the pinhole size leaks on the side walls of my specialized tires. I followed the directions step by step and watched the youtube video. I just keep adding air, shaking and flipping the tires. About 8 hours inflated and 75% of the leaks have stopped. I hope this isn't a waste of money.

Was told when I purchased my Giant Anthem 29er other tubeless conversion strips were needed. The always lost pressure between rides. After buying and installing the stans conversion strips and liquid they now hold pressure between rides even using the non UST tyres I race with.

Put it on a SUN RIM CR18 had a hard time putting on the kit using a floor pump(no Luck)but once i used a air compressor it went on in less than 5 sec.
My bike feels a lot lighter NO MORE TIRE STRIPS, SLIME TUBE with thick walls.

As above. Even the bike shop had to keep it an extra night, to re-do the front tire. They said the Spesh tires 'can be finicky'. But...it WORKS! Came back from a ride last evening, pulled out FOUR goatsheads from my front tire. Every time I pulled one out, it hissed for about 2 seconds, a drop of milky fluid came out the hole, than that sucker was SEALED. Repeat this 4 times. The stuff flat out works. My tires are still hard this morning. I'm sure I'll have to refresh the levels every few months, because it does dry out eventually. But I am sold. I think when you're getting that bead set the first time, it needs RAPID inflation; read:"compressor". If you don't have one, or are not that experienced with tubeless, it's worth the money to pay a wrench to do it right. After that, you can maintain it yourself. Recommended.

I like this more than tube tires but I guess what you like is going to work for you best. I prefer to use stans thought over tube's. You need to know how to install tires if you are going to purchase this product.

easy install with air compressor, lightens wheels quite a bitespecially if your running dh rims and tiers, lots of extra sealant if you want to change tiers, no pinch flats I hope.

DO NOT BUY THIS PRODUCT! Save your cash and sacrifice the few grams of weight and by Slime tubes. I have lost hours of ride time over this Stan's "No" performance product.
