The only complaint I have is 1 3/4 hose doesn't seem to work right. I used 1 3/4 as well as 1.75 and neither worked correctly. Any suggestions? Other than that it works well.
Waste of a dollar. Should be free.
Thought it was better detailed and does not allow you to use proper hose sizes. So pretty much useless.
Drop down screens with hose sizes and common lengths of hose lays would be great.
