I love it. Don’t know why everyone doesn’t do it. Commuting with light weight and no flats, its very nice. (much lighter weight than the Marathon+_



It does have some drawbacks. Tires loose air faster, needs maintenance (sealant refill every 6 months), can be a nightmare to mount the tires on rims as there is no reall standard (this is really hit or miss). Tires need to be rotated regularly (i.e. winter) or the sealant will dry out in one spot. Works best on tires 40mm or larger (as in many cases going over 60psi can be dangerous). Still, for commuting, its wonderful for the safety, piece of mind, and ability to run softer pressures.
