The prior reviews on this product looked very good and the price was simply GREAT. But, alas, the price was again, to good to be true. Each light comes with it own set of rechargeable batteries and putting the lights together is a breeze. But, like most non-wired lights, these don't put out much illumination and even on full sunny days about a third of the lights can't muster more than a half-hearted glow for a few hours at night.The clear lenses produce a pleasing soft light blue illumination. If the lights are placed about 18" apart, they may be suitable for lighting ground cover and walkways, but don't expect more from them. However, they are a tremendous value. At less than $7.00 each, they are still cheap if only half of them work effectively.
