Frequently asked questions on this topic

For our upcoming test series 'Always on the go - always hydrated' we had or have another insulated bottle, or according to the manufacturer insulated mug, in the long-term test. The insulated mug from Diller with 230ml capacity (this size is currently not available).
Whether the small size is also practical in everyday life and everything else from our test in the following text.

The Diller insulated mug has a very practical size. Clearly, the filling quantity is not enough for extended hikes or bike tours. But for an iced coffee at the bathing trip or a refreshment in between, it is perfect. The drinking bottle is 100% leak-proof, but not for carbonated drinks. The mechanism of the lid is practical - when operated correctly. The sliding mechanism 'disables' the opening mechanism - by pressing on the lower part of the slider, the lid pops open. The drinking opening is practical and allows comfortable drinking.

Rienigung should be done by hand. However, since I often use this insulated bottle for coffee and I am also extremely lazy, I also always clean this cup incl. lid in the dishwasher. After a few cleanings, however, the outer coating begins to dissolve - does not look nice, but does not bother me and the function is still maintained. Also, the tightness has not diminished after more than a year.

My rating
A VERY GOOD with the restriction of the cleaning option. Who is not bothered by this, should be satisfied with the insulated mug.

My name is Martha, and I am a 38-year-old former freelance journalist. After a successful career in the journalism field, I decided to make a significant change in my professional path four years ago and pursue a new career as an elementary educator. Since then, I have been passionately working in a daycare center, thoroughly enjoying accompanying children in their development and supporting them on their journey of growth and learning.

I appreciate the daily interaction with the children, which offers me new perspectives and valuable experiences. Through my work as an educator, I have deepened my understanding of the needs and challenges faced by young people and acquired numerous valuable skills that benefit me in both my professional and personal life. I am happily married and the mother of two fantastic sons, aged 7 and 10, who inspire and enrich my life every day.
