Love it! I didn’t give it 5 stars due to the following. 
I probably spent over an hour trying to figure out the malefemale extra tubes attachments. 
It would have been helpful to mention that the knots are exchangeable. See picture 2 - spare tubes. When on, you cannot tell they come off. Other than that. It’s beautiful, I even figured out how to work out the offset of my home electrical box that for some reason it’s not centered.
