The BS is very well made, the instructions are good. We were amazed at the good effect, previously a 3 kw BA was installed in a 160 tunnel. The new one has at least the same effect at 2.4 kw in the 140 tunnel.
Ladies and Gentlemen, am very satisfied with the goods. But would also like to mention Mrs. Gerdes, because she is very competent. Sincerely, J. Sygulla
