Tried this as an alternative to Stan's. Sealed up some TL-ready tires (UST bead) on a Stan's rim with a floor pump, so that was a good sign. Injected it into the tubes of other bikes and they started to hold air better, without losing pressure over time.Was able to ride my local trails without immediate flats, riding home and finding numerous thorns in my tires. Sometimes they went flat overnight, but pumped back up okay, even if I left in the thorns.When I pulled out the thorns, that's when its bad traits come out. It cannot seal a puncture from a full goathead very reliably. It will make a huge mess, shooting sealant out. I got some of on my workout clothes and it doesn't come out; [*].I've managed to flat every tire/tube I've used it in, over the past few months. I've had far better success with Stan's. It's a huge mess inside the tire and the tube is coated in ooze.I *highly* recommend staying away from this stuff.

If you're using thin(er) side wall tires this product will not seal as well as Stan's. I was using the same tire front and rear and could not get the rear to seal, even after two weeks of riding and re-inflation. Took out the Caffelatex and installed Stan's. The Stan's sealed on the first try!

Lets admit it, none of us really love working with Stans Sealant even when you have the set-up mastered as it creates a mess. But it works once it's in and as we all know is far superior to tubes.

I decided to try this Caffelatex to see if there was something better out there. There isn't, at least this brand isn't. It's a super thin fluid so makes even more of a mess during set-up.

But the big problem is that it simply doesn't seal as well as Stans. And this is during both set up and riding. After many attempts of getting my tires on the rim I finally stopped the air from leaking out, but with the messy stuff all over the place as it hissed out and sprayed all over the place. The fluid would simply peculate out and not close up the small holes Stans seals instantly.

But even worse...the ride. It leaked out of three separate, small areas, and never sealed, the bubbles they advertised? Well it just bubbled and bubbled and didn't stop. In fact it created these big globs on the tires after it dried. I ended up putting a tube in and when I got home threw the big bottle of CaffeLatex in the trash can....Back to Stans.

This stuff is terrible. It doesn't seal punctures, even small pinholes, at all. All it does is spray out in a fine mist, regardless of whether the wheel is kept spinning or stationary.I went back to Stans, which works much better.

I live in a extremely dried/hot area, 75~80f during spring, on summer we can reach 110f, I read that results depend on weather, I tried in a pair of used tires, the tread good enough to discard but the inner rubber was too porous to use tubeless, I applied the minimum amount of sealant, only 80ml per tire, air pressure pushed sealant out of the tire and seemed that it was not working, but instead of dripping, it sealed in less than 10 seconds, even the largest punctures that stans was not able to seal. Air pressure is still good as the first ride, so far happy about the product and I highly recommend caffelatex.
