Three days after a very fast delivery I have to write my opinion today. The brush is just great. My two Newfoundlands are absolutely satisfied. They are as if nailed and are rather disappointed when it hot: ready. To 15 minutes instead of previously 1- 1.5 hours - Degree per dog 20. Barely hair on the floor. and through the already mitabsaugen the dander still 2 times brushing significantly scrape a few. As said by brushing 2 times I am totally satisfied. I hope this brush keeps some time. But even after 4-5 months I would buy the same part again. For me the time advantage the money is absolutely worth it.
