It looks like a lovely product but for tubeless tyres, you have to produce a high volume and pressure initial burst of air to pop the bead into place on the rim and seat the tyre so it holds air, without the air coming in through the valve just leaking straight back out around the edges of the tyre. You lock the outlet on the pump and then pump to pressurise it in an internal chamber, and then release it all at once.
Like this one which is a similar price to the Silca https://www.topeak.com/global/en/pro...OEBLOW-BOOSTER
