Received this from Silca after making a warranty claim. No hassle or fuss, and they were even helpful with making the claim correctly, which was refreshing these days. I haven't had to use this version trailside yet, but love the addition of the control knob when testing at home. Nice to see a company really stand behind their products and not hide behind excuses. Certailnly makes me feel even more confident when buying Silca products in the future.

Hervorragende Qualität & Bedienbarkeit - funktioniert immer & hält den Druck einer angebrochenen Kartusche, top!
Sehr handlich, perfekte Ausstattung für den Notfall - wegen tubeless nur bis zur Ankunft zuhause um Verklumpung durch CO2 zu vermeiden.
Auch das „Ploppen“ des Reifens auf die Felge konnte im Notfall bereits mit Eolo realisiert werden - mangels Kompressor zur Hand, spitzenmässige Dosierbarkeit!

Great inflator. I am not sure if it is. . . but it seems to be the most compact CO2 inflator on the market.
