pity that there is no greater

The biggest advantage of the device - small, light, handy - unfortunately is also its biggest drawback. Although I miss the comparison with other devices, but slightly larger should be the water container like. It would be best if our diving masks fit into it ... Well, you can still dream;)

After all, you can two glasses at the same time clean it if they are not wider than 14 cm, and with a drop of detergent in the water they are wonderfully clean. Without detergent cleaning performance, however, was close to zero. Since I only have glasses with plastic lenses, I appreciate especially that the cleaning in the ultrasonic cleaner carries far less risk of scratching the glasses, as any kind of manual cleaning. That alone to me was the acquisition already worth.

I tested the unit also with small parts: coins, keys, silver jewelry, toothbrushes, the Fusselsieben from the kitchen sink and the lids of two thermos flasks, one for coffee, one for tea. In particular, the test result with the thermos lids was more than convincing: I know that it is always some deposits, which one elicits only with daily rinsing, shake vigorously and ejecting, but what the Grundig UC 5020 because after such a "treatment "has brought out (without detergent addition by the way) - Good for you!

You can also clean CDs and DVDs with it, but here is a real shortcoming of the device. The cleaning process instructions automatically ends after five minutes, CDs and DVDs should you but lt. No longer clean than two minutes. So you is "rifle at" so that you can turn off the ultrasonic cleaner in good time. Because I wanted a two-stage timer or the (simpler) solution that basically any cleaning only takes two minutes. What takes longer, would give more often cleaned in succession. That would hardly constitute a smear at ease and would be less risky.

Conclusion: The thing is good, strong buy recommendation, just a pity that the cleaning tank is no greater and a two-stage circuit is missing. There's a star deduction. Oh yes, we have actually two members of our family who are facing the device extremely skeptical: our cats. The probably hear more than just the twang that perceives our kind.
