This is a good quality product.  It comes with a clamp mechanism that can be placed at any point along its length to adjust the watering length, but it is somewhat troublesome to move from one point to another.  One drawback is that the holes in the sprinkler side are very small, and the two sides are hard to distinguish when laying it down.  I marked one side with a permanent marker to help get it oriented as I wanted (soaker or sprinkler).
