This pump makes seating tubeless tires very easy on road bikes. It was impossible without it. I was able to seat 4 tires very quickly and single attempts.
However, the pump doesn�t seem to form a great seal with presta valve. When using it to fill air it seems to leak air at the nozzle.
The integrated chamber is a lifesaver if you run tubeless. I tried just pumping fast with a regular pump, just to see if I could seat my tire and there's just no way. It was pretty much a snap with this pump. I also just plain favor it over my other pumps for every day use. Expensive, but well worth it to me.
I was using C02 cartridges to seat tubeless tires which is wasteful. This pump is a much better alternative.
