### ⭐⭐⭐⭐⭐ Super Qualität kann ich mit gutem Gewissen weiterempfehlen
*by B***T on 19 April 2026*

Ich bin super zufrieden so wie es sein soll kalt bleibt kalt und heiß bleibt heiß. Ich habe schon die zweite gekauft weil ich zwei Flaschen mit ins Büro nehme. Sie sehen au super aus besonders die hellblaue. Ich kann sie mit gutem Gefühl weiterempfehlen.

### ⭐⭐⭐⭐⭐ Hält was es verspricht!
*by I***. on 23 June 2020*

Ich habe die so eine Trinkflasche in orange vor einem Jahr als geschenkt bekommen. Und ich bin bis heute sehr zufrieden. Nutze ich täglich, auf der Arbeit oder sei es beim Wanders. Und sie halt was der Hersteller verspricht. Im Winter war der Tee immer noch heiß trotz Außentemperatur um die 3 grad herum. Oder zur Zeit nutze ich als Crash Eis Speicher um auf der Arbeit kalte Getränke zu trinken. (Mischen) So jetzt kommt das aber, ich würde diesen Artikel nicht über Amazon bestellen. Da der Artikel lieblos verpackt geliefert wurde an die Packstation, so dass die Flasche ein paar Kratzer hatte und als Geschenkt für meine Freundin nicht mehr in Frage kam! Schade eigentlich, da dich meine Freundin dich die Flasche auch so sehr gewünscht hatte in der Farbe Avocado.
