H2D Hair Straightener Linear 11 Cool Grey

What’s the buzzing noise I can hear in my H2D hair straightener?
The H2D Hair Care Linear II Hair straighteners have an ionic generator component. It is u for your straightener to make a buzzing sound. Please don't worry!
My H2D Straightener plates don't seem to meet.
That's perfectly normal. All H2D hair straighteners have floating ceramic plates. When the hair straightener is turned off and not in use, there will be a large gap between the plates. Once the straightener is turned on, the gap between the plates will close up but not completely. Our technology ensures that the ceramic plates never touch one another and cause damage to the plates. Instead, the hair will glide through the floating plates.
Is the temperature adjustable in the H2D Linear II Straighteners?
All H2D Linear II models have adjustable temperature control. 0-230 degrees.
What are the plates made out of?
The Linear II range has ceramic plates.
Is there a difference between the colours of the products?
No, all of the H2D Hair Care Professional Styling Tools have the same technology; the only difference is the colour.
