Easy to set it up, wired up and connected to my battery bank without issues. Comparing to my previously installed TPW-400DT (which cost me $700), this one seems not catching up wind direction all the time. TPW-400DT runs consistently catching the wind direction, but this one quite often interrupted (facing opposite direction of the wind) after running a while. As other people pointed out - the tail may have design flaw - maybe some fixings will help that? Comparably it is not so noisy even gust wind speed is above 25 mph. I will see how it does after running for a period of time. The rubber pad coming with the package is quite useful to bind my pole to the wind turbine -- I used 1 1/4 inch galvanized pipe with joint on (which is 2 inch OD) . With this price tag, it should be a worth buy.
