Review on Control Water Flow with Two Little Fishies ATL5445W Ball Valve - 1/2-Inch for Effective Regulation by Beth Martin

I use these to cut off the visible nose on my Waverunner. Fish are great at that. Unfortunately they break if you try to turn the handle the wrong way. However, I gave it 5 stars because of the low price. If you use the product very carefully, the valve will work well and easily. Personally I would have preferred better quality at a higher price but for my purpose this is still the best product I could find. I don't want to use anything that will corrode in seawater.
