Really pleased with the product, my only feedback would be that you might want to consider putting a few extra nuts, bolts and cups in especially when is coming from such a distance. Two bolts snapped for me as I was putting the item together even though I used the same torque setting for all which makes me think they were faulty. Also one cup has a small crack in it so again a couple spare would of been appreciated.
Cheap plastic & will fail after a few months of high pressure & temp changes
I CAN'T recommend this product. I won't even use it because I'm certain it will fail in a few months of use. As an engineer it's my job to design & study equipment. It's plastic & while it may not rust it will certainly become brittle & crack hence fail with temp & pressure fluctuations. This may work as a CHILD'S experiment but NOT as a real part of generating electricity via hydro.
