CM-9521A April 10, 2017
Reviewer: Steven from Ontario, Canada  
Unit is well built, manual is lacking in that in setting the unit up, your have to sync the rotor, this gives a flashing 5Y4, and if you are patient enough, it will step down to 3,then  2 and finally  to1

There is no explanation as to what is going on.
All the time the motor is humming, gave me the feeling that it might burn out.
Apparently this is normal, just not explained.

Other wise this is a good product.

Reviewer: Anonymous Person  
I am very happy with Channel Master's products.
I have used their products for 30+ years and would not consider using any other.

Antenna Rotater November 28, 2016
Reviewer: CrankyOne from Camas, WA  
This is really heavy duty and easy to install.  I have a large TV antenna on it and not had any problems.  It does a good job ranging for channels and has good pre sets.

A Must for Antenna Fans, but... November 25, 2016
Reviewer: Wolf from Lovell, Maine  
A reliable and accurate antenna rotator is definitely a must for the rural TV viewer who wants to take advantage of the crisp digital signal available over the airwaves. This product seems to work once properly set up. Unfortunately, the setup instructions are printed overseas somewhere on what is supposed to be product manual but in fact is the worst kind of technical instruction sheet I have ever seen. Printed on low budget stock, it is printed almost illegibly small, difficult to comprehend and dispersed among foreign language instructions over several pages.  I ended up writing myself a summary so  occasional visitors others could grasp the manual. I am not able to comment on the rotator's reliability but it looks rugged and should withstand the elements. Another flaw was the fact that the technical description does not specify the fact that special (22g AWG) wire is required carrying an 18 V to the unit. In summary: a promising product poorly marketed and set up.
