Quick delivery under the circumstances. Dimensions are ok and self adhesive surface was easily attached. Effective insulation sped up bed heating times noticeable.
Well the one I received is no cotton/Baumwolle but some foam. Since it does not smell and is heat resistant I dont care, but should be advertised as is. Needs rework to fit the printer. Adhesive can not be removed easily. Interferes with rear drive (too thick) on Ender 3. Do not realy recommed .
