Seems to be a excellent produce, well made and works as stated. I just wish i could have mixed the colours and got a slight discount as I ordered 6 lights, 4 white and 2 green, instead of being charged £58 for 6 lights I had to pay £62 for 4+2. Other than that I'm very pleased and I'm praying they are reliable as they look great set into my block paving. Also maybe you could design a product that makes it easy to lift the blocks from the paving to access the on/off switch and the battery a little easier, maybe something along the lines of a sucker? like a toy gun dart that you can easily stick to the top and lift the light enough for you to get hold of. I set mine on a sand base in the hope that excess rain water drains away from under the light quickly to protect the electrics as much as possible.
