The product

The Straightening Iron by Udo Walz by beurer comes in an appropriate packaging. The straightener has the typical simple design and is supplied in black. When unpacking, however, it was noticed that the surface of the straightener showed slight scratches.

There is no display. The temperature is adjusted by means of a temperature control (small wheel). This smoothing iron also has a useful plate lock and a cable with a swivel joint. It turns off automatically after 60 minutes.

The device is switched on with the on/off switch. Then the operating light starts flashing. It takes approx. 30 seconds for the unit to be ready for operation at the lowest temperature level. As soon as the desired temperature level has been reached, the operating mode flashes continuously red.

The temperature levels for this device are between 140 °C and 230 °C. The temperature range for this device is between 140 °C and 230 °C.

We used this straightener on thick, wavy hair. After a quick warm-up time at a temperature level of 230 °C, individual strands were smoothed. Result: The strands became very smooth and supple after only a few times. The device is easy to guide and very handy. There was no hair loss, as the individual hairs did not settle in the plates. But the fact that this device is very simply equipped in terms of its functions, the result is still impressive. In addition to smoothing, good waves can also be achieved.


This product may also only be cleaned with a damp cloth. Clean the plates carefully, as otherwise scratches can quickly occur.

We have evaluated approx. 150 reviews on the Internet. In summary, it can be said that about 80 percent of buyers are satisfied (4 stars) or even very satisfied (5 stars). Partially (2 stars) or completely dissatisfied are approx. 10 percent of the users. The average score at the time of the evaluation was 4.3 out of 5 stars.
