Product review (3 stars): Great for ranch duty
I bought these hoses because they are made to be under pressure, meaning the water valve is always on.  I am a rancher and I find that these four foot rubber hoses work great for several of my automatic chicken waterers.  I located the water supply lines close enough that this length is just right for ranch duty.  They have held up well for the past few years through rain, heat, and freeze, but this last freeze was a little too much for one of them and the thread split.  I just bought some more so I can replace that original one and have a few on hand just in case.  Hope this review helps.  Rob
