  A great addition…

  I picked this up for the bottle I use for protein shakes and smoothies. Any dairy can be a little tricky to clean out of more complicated lids. This one is a dream to clean in comparison. Works great.

  Plus pratique

  Permet de boire plus facilement en marchant ou lorsqu'on est en voiture; j'ai changé mon bouchon d'origine par celui-ci et c'est parfait.

  Great idea, terrible execution

  You would think they would use a standard tread pattern for their cap… but they didn’t. It doesn’t even fit wide mouth bottles from the same brand. Would not recommend.

  Good cap

  Appreciate using this on the wide mouth bottles so I can put in larger ice cubes and not have them come out while drinking some ice cold water.

  Helpful option

  Useful to have the option to drink from a smaller opening. Maintains spill-proof seal.

  A must have cap for wide mouth bottle

  Good quality, and found it is lighter then original wide mouth cap. Not sure if it is good for hot water.

  Great for water bottle.

  I originally bought the wide mouth bottle with coffee sip lid. This is great to convert to use as a water bottle and cold brew coffee.

  Remplace bien le sip lid

  J’ai deux bouteilles à café avec l’embout “sip lid”. Le cercle de silicone se perd facilement et n’est pas disponible en remplacement. J’ai donc opté pour ce capuchon qui fait la job.
