Product review (5 stars): Easily installed, does what mfgr claims, sturdy - Buy It!
There are imitations on the market - get THIS one - easy to install and it works as advertised.  This replaced a very old Deflecto product, which was cracking up (literally).  The local h/w stores have limited selections - one item "looked" like this, but I was glad Amazon had reviewer comments that steered me to the Heartland brand.  The internal pop-up on this is much better designed and should last many years.

I painted it, but as a precaution wiped the plastic down with vinegar beforehand.  I like the idea that it is higher from the ground level and therefore less prone to being bumped by the lawn mower.  I also added a piece of 4-inch vent pipe as to better transition the bottom part to the existing vent pipe, as the original installation was a bit recessed to the building.  Good product!
