In our test, the thermal drinking cup from GRASSHOPPER made a very good impression. The thermo mug with integrated straw and mouthpiece guarantees easy and leak-proof drinking. The product has a filling volume of 500 ml. The good insulation of the bottle is also excellent, so drinks stay at the desired temperature for a long time. Another advantage is that the Thermo Mug is leak-proof; in our test, the Thermo Mug did not leak. However, the Thermo Jar is not dishwasher-safe, otherwise the quality suffers. However, this is normal for thermo containers. Unfortunately, the seller’s contact and address details are missing, which would have been desirable.
Advantages
✅ Integrated straw with mouthpiece
✅ 500ml filling volume
✅ leak-proof
✅ Easy and leak-proof drinking

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Product protection | Carton is sturdy, product sufficiently protected | 100 points |

The GRASSHOPPER thermo tin arrived in a Deutsche Post shipping box. The box was undamaged and easy to open without any tools. Inside the box, the thermo mug was wrapped in a very thin plastic film. The foil might not have been necessary, but it protects the thermo mug from dirt and scratches! In this case, the product was fully protected and the thermo mug was therefore in perfect condition.
The packaging of the thermo jar is partially recyclable. Unfortunately, the plastic film is not recyclable, but the shipping carton is.
Overall, the GRASSHOPPER thermo mug makes a very good impression. The thermo mug was not damaged and the package was in good condition.
After unpacking
Package contents and instructions
ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

In addition to the thermo can with integrated straw, the product box contained a replacement straw and a cleaning brush. The cleaning brush is suitable for the straws.
The instructions for use and the hazard warnings are printed on the box. This means that no additional material is required for an extra leaflet. The instructions for use are written very clearly in German. There are also additional printed pictures explaining how to use the mouthpiece.
Unfortunately, there is no address or contact information, which would have been desirable. Only the company name is printed on the box.
We also received a spring sponge from GRASSHOPPER as a Christmas present.
All in all, however, we think this is an extremely well thought-out and customer-friendly way of sending a product.

The thermal drinking can from GRASSHOPPER makes a very good visual impression. In addition to the simple black design, it has no manufacturing defects. The thermo mug is available in a black or white design. The thermo mug is made of high-quality stainless steel and should therefore not be cleaned in the dishwasher.
The thermo mug has a filling volume of 500 ml.
Another advantage is the low weight of the mug and its sturdy, high-quality finish.
Unfortunately, we cannot find any information about sustainability, but the materials used appear to be of very high quality. Due to the high quality, a long service life can be expected.
This is what our practical test showed

It’s super easy to use, just fill it with the drink you want, close it and you’re done. Depending on the liquid temperature, you can drink immediately. (Caution with hot drinks)
The GRASSHOPPER thermo mug is suitable for hot, cold and even carbonated drinks.
Even after our test phase of more than 7 hours, the drink was still very warm and hardly lost any temperature. Even chilled drinks are kept cold for a long time.
In our test, the GRASSHOPPER thermal drinking jug is completely leak-proof; no liquid leaked out even when the jug was turned upside down or shaken.
The integrated straw with mouthpiece guarantees easy and leak-proof drinking. This cup can therefore also be used for children without any problems.
Due to the material used, cleaning in the dishwasher is not possible as with other thermal containers. The straw can be cleaned using the cleaning brush supplied.
