SIGG - Screw Top White Screw Top - Replacement Cap (One Size) Water Bottles with Narrow Opening or WMB Adaptor - Leak-Proof - Swiss Made

Works great. Keeps the water in my water bottle. Stops negative space from entering .. I guess? It's a bottle top. Does what it's supposed to do..

Bought and paid for, fits perfectly. The only reason i bought this $9 screw top in a color I don't like is because the other colors are cost as much as a whole new bottle.

It fits just fine. I just think the price is too much for the product.

Great product and fits the original but the price is way too much for a screw top cap

Fits as it should, with a tight seal.

Fit perfectly and isn't nasty looking like my old one was.

Works.

Fits like a charm!

I'm tired of buying these. Whatever I do they end up mouldy. The latest one lasted about two weeks before there was a discoloured ring on the rubber. Really annoying that there's no way to change just the rubber – I need to buy the whole thing again. Pleasant design, Sigg, but if you have other options, don't waste your time.

Good simple top for Sigg bottles.Bought to replace the fancy twist & suck through tops that came with our two most recent Sigg bottles, which sadly do suck - they dribble & leak in use and when closed.Keep It Simple Stupid - would buy one again.

Never had mould appear on any of my sigg lids, and my last one was also white.

Doesn’t work.

Nach wenigen Wochen (bei täglichem Gebrauch), beginnt die Dichtung zu verschmutzen (trotz täglicher Spülung, und nur Leitungswasser in der Flasche). Am Foto ist das Ergebnis nach ca. 6 Monaten. Mit der Zeit schaut das dann nach Schimmel aus. Das ist schon der zweite Verschluss den ich innerhalb eines Jahres gekauft habe.Ich habe meine Sigg-Flasche über 10 Jahre. Die Dichtungen der damaligen Verschlüsse waren aus einem anderen Material. Da bin ich ca. 10 Jahre mit dem Originalverschluss ausgekommen (der nie verdreckt ist).
