I have been purchasing the 'ice cubes' for a few years now and have been very pleased with the effect they give. The only down side is that as they are fitted loose in the pathways over a period of time water does seep in and rust the solar battery.I feel the lights could be more watertight, but as a suggestion I wrap tin foil around the bottom of the light which does help. and you can buy replacement batteries. With the string lights..which look great...is there no other way of showing the on/off buttons ? the switches are obviously covered and you have to press for on or off...but there is no indication as to whether you have switched them on or off. I can't priase Customer Service enough. Whenever I have called them they are always very polite and helpful.
