So happy to have found EcoFizz! We'd been buying gas cylinders from Amazon and Servei Estació for a couple of years, but every time we went the price seemed to double. It seems to make economic sense again now since we've found ecofizz - service is fast and relatively simple. So far, so good!
An extremely quick, easy and efficient way to get gas bottles, meaning you can make your own fizzy water at home. No plastic, no supermarkets. Clean and eco-friendly.
Excelente servicio de recambio de botellas de CO2. Precios competitivos, gestión rápida de entregas y devoluciones, y muchos puntos de recogida donde apoyarse. Las botellas vienen muy bien llenas, por lo que dan para gasificar un montón de litros de agua. Muy recomendable.
Llegó super rápido, muy buen producto. Muy buen precio comparativamente con el mercado. Estoy encantada!!
I've been using EcoFizz for a while and have always been really happy with the service. Deliveries are reliable, the setup is convenient, and it's a great way to enjoy sparkling water at home without constantly buying bottles. Friendly team and a genuinely good service.
Le service client a été très réactif à chacune de mes demandes. Ils ont également repris mes anciennes bouteilles, ce qui est très pratique. En termes de prix, ce sont les moins chers de Barcelone. La livraison et la récupération des bouteilles se font directement à domicile, ce qui est un vrai plus. J'en suis très satisfait et je recommande vivement leurs services.
I am very happy to have stumbled upon EcoFizz. I was really looking for a good alternative to Amazon for this sort of purchase, and here I also have an option to reuse and recylce the cylinder... The service has been fast, efficient.. very happy with the company and service
