I just got my Bell and Howell Solar Powered Lights.  I really love the way they are so modern and classy looking.  The stainless steel look is really sharp.  I first soaked the ground good so that they sink into the ground easily.  I pushed them into the ground with my thumbs in the very center, then used my foot to finally set them.  I spaced my planter walk area with one light every four feet.  Adds a finished look to my planter/walkway, and adds safety for no trip/stub your toe.  The design has a low profile that does not stick up out of the ground, and the construction looks very durable for a long time of service.   No wires make for easy installation, and no batteries means no money to spend for energy source.  Think if they were battery powered and how much of a pain that would be.  Very happy with the solar energy source.  Overall great product, and I highly recommend.  Thank you.
