Review: Toppen - Flaskan isolerar toppenbra och sugröret funkar som utlovat samt är 100% läckagefri. Enda nackdelen, för mig, är att flödet inte är så högt i sugröret. Så är man törstig tar det tid att få i sig tillräcklig mängd vatten. Men tror det är väldigt individuellt vad man föredrar.
Review: Bien !! Rien à redire - Solide et garde au frais!! Très pratique
