I'm not 100% sure, but it's far better than the one I had before. The adjustments seem to work.
You can not attach more units to this style sprinkler.

Mine is 40 psi.Works just fine.City water pressure is 50 to 60 psi.
The "Turbo" is just a marketing label. I think it's just to reflect the generous number of features, or an improved oscillation mechanism. There are no electronics. It's just water driven.
We only test to full range position for the largest area coverage
Yes there is a minimum water pressure requirement. You will need at least 40 psi at the sprinkler coupling to get the near the 4000 square feet. Please remember that the length of the hose does reduce the psi at the tap.
What price are you seeing? I purchased it online for $26.52 on July 17th. It is worth every single penny! I especially like that it has a heavy duty metal base. It keeps the sprinkler sitting flat and level on grass.
