What to know before buying
Listing details to confirm

Confirm the selected listing’s cylinder quantity and capacity interpretation before purchase.
Who is it for?

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller portion are low ratings. Without customer comments, the reasons for either positive or negative scores are unknown. For a cylinder purchase, the unresolved quantity and capacity wording is more actionable than the ratings alone.
Frequently asked questions
How much CO₂ does the listing say the cylinder holds?
The description states a filling capacity of 425 g. The details also list a capacity of 240 Liters, so the listing does not make clear how those figures relate.
How many cylinders are included?
The quantity is unclear. The title uses the plural “Cylinders,” the size field says “4 pezzi,” and the item count is one. Check the selected listing for the actual package quantity.
Is this confirmed to fit every GROHE Blue system?
The listing associates it with GROHE Blue but does not specify compatible system variants. Confirm compatibility with your particular setup before buying.
