These solar powered path lights are very attractive and quite bright. When attached to their in ground stakes they sit almost flush with the ground and are low enough to easily be able to be mowed over without damage.  The only fault I found that led to the four star rating is that they are only loosely attached to the stake and can rather easily be kicked off inadvertently.  That being said they are easily reattached if this happens.  All in all a nice product for marking a path.
