Have the brush now less than a month in use and receives from me a strong buy recommendation. It consists entirely of bamboo (according to the manufacturer from sustainable sources). Even the bristles are hygienic prepared bamboo bristles which have a very pleasant hardness (previously no gingival injury). The bristles are arranged in four rows in thin tufts, which I reach a very convincing cleaning result. The wood is processed clean and felt nearly frictionless on the cheek inside (but noticeable than plastic). The brush head is running to oval and is held pleasant narrow, yielding easily comes up to the rearmost teeth. The handle is flat, wide and almost as long as in a conventional plastic toothbrush designed, making it even is very pleasant for me as a human being with larger than average hands in hand and must be kept. Packed is the brush in recycled (wax -?) Paper and a cardboard cover.
Compared to my first tested wooden toothbrush from another manufacturer absolutely and unreservedly recommended and their higher price all times worth. I sincerely hope that such a very well-made "eco-brush" will soon be standard and the plastic in plastic in the mouth soon be consigned to the past.
