Compare Bosch PFP 1136 Beurer HK 30

I have the heating pad Bosch PFP 1136 and Beurer HK 30 and would like to compare this.
The Beurer indicated with 100W and 60W with Bosch. The Bosch is each about 2 cm larger in length and width. The power supply lines are roughly equal in length. In the corner where the power cord is discharges into the pillow to feel both a thickener, at Beurer is this "junction box" larger.

The Bosch pillow feels a little fluffy. For the Beurer is faster and more warm. At Bosch, you can feel the switch position if necessary to 1 to 3 points, but you can see the position of the Beurer glow in the dark.

Neither pillow smells cheap, only slightly new.
When Beurer could remove odors from cushions better because the pillowcase is washable at 40 degrees and below the heater is located in the wipe-clean plastic. At Bosch the cover is washable even at 40 degrees, but the heating is sewn into fabric.

Since the Beurer HK 30 with 100W really fast and become warmer than the Bosch PFP 1136 60W, Bosch gets the only four star.

In my PFP1136 me a slight buzzing sound is additionally noticed the always starts about 2 seconds after switching on. This hum I do not know from my Beurer heating pads.
