It's good quality, easy to assemble and performes well.

Very Pleased with this Small Wind Turbine Generator Likes: 1. Wind Generator is SMALL 2. Wind Generator is POWERFUL 3. Wind Generator OUTPUT Voltage and Current can be adjusted depending on your setup and how you use this Wind Generator 4. Generator comes with SOLID METAL GEARS of different sizes for Wind Generator Rotation Speed Adjustment Dislikes: 1. All Gears provided Do Not have "D" shaped holes with a lock bolt

It was good for the 4 sprockets to be assembled in the box and to have a crank

Maybe poor transit handling. Maybe it slipped past Q.C.. Anyway, should be okay for well supported vertical arrangements until failure. Perhaps, the addition of gears properly aligned in your custom gearbox could pick up some slack. Otherwise, it's on you. Go kick butt and good luck out there!

The generator turns by hand with a little resistance. Unfortunately that resistance proves too much once the 4 gears are attached. The torque needed to turn the generator with the gears is greater than my efforts of about 30 pounds. Didn’t even budge. So theoretically the generator might be able to produce 12v, but this gear set up doesn’t do it. Before posting this I contacted the seller and did not hear back.

Dead on arrival. Also, the gears appear to be made of lead and shedding lots.

Well made quality product
