## Description

GX Pump CS4-I compressor

Review: Any good - Excellent product excellent service brilliant machine very quiet fills at a nice slow fill thanks again Keith
Review: Hatte zuerst eine defekte Version erhalten, der Austausch verlief jedoch problemlos. Der GX PUMP GX-E-CS4-I überzeugt nach dem Austausch durch seine solide Leistung und einfache Handhabung. Der Kompressor ist tragbar, lässt sich gut transportieren und ist schnell einsatzbereit. Besonders hervorzuheben ist, wie leise der Betrieb im Vergleich zu anderen Kompressoren ist. Die Verarbeitung wirkt robust, und die Bedienung ist unkompliziert. Für PCP-Nutzer, die einen mobilen und leistungsfähigen Kompressor suchen, eine klare Empfehlung. Preis war am 11.10.25 594,15€.

*by T***B on 10 December 2025*

Soooo glad I bought this compressor! In recent months I've bought three different budget level compressors and had problems with each of them (wouldn't work, or did but abruptly stopped working etc.) and so returned each of them; which I really don't like to do as it takes added time and energy. So I decided to spend the extra money on this one, hoping for the extra cost there would be no more issues... and I was right! Three or four times more expensive than the others but definitely worth it to have ZERO issues! Works like a charm. Highly recommended.
