Hiya, I use it in all of my bikes (3 of them), both tubed and tubeless tyres. No problem with it at all, there are slightly different versions available for each type of tyre but not sure what the difference is if any, doesn't seem to make much difference lol. On the 660Z which I do a lot of green laneing on I nearly always find several punctures caused by thorns that have sealed when I remove the tyres. The most has been 4 on one lane where the thorn hedge had been freshly cut... tyre was soft but not flat and top up of air lasted rest of the day.
Only thing to watch is that the tyre can't be balanced properly, mostly a problem if you refit a tube that has already been "slimed up", the other I have noticed is if the bike has been sitting for a few days between rides, the slime settles and takes a mile or two to get redistributed.
As it is water soluble tubes can be wiped/dried and patched without any trouble, my local tyre fitter seems happy enuf as long as I tell him the tyre/tube is treated before he removes them from the rim.
Well worth having as far as I'm concerned.
Cheers.
