Question: I wish I bought these sooner. I noticed a significant savings in just a month as I used to leave to lights burning 24/7 in the front and back yards. These LED lights are very bright in a positive way and help me to easily see my front driveway area as well as my back patio area in the back.

Answer: positive

Question: After reading reviews, I thought I would order 2 sizes up. Normally I'm a L/XL, so I purchased a 2X figuring it would fit! To my surprise, the shirt was way too small. It fits my sister who is a size small. The material was not cotton as I thought, but 95% spandex. I'm very disappointed as the shirt is very cute. Instead of returning it, I gave it to my sister. I would recommend ordering 3 or more sizes up from what you normally wear.

Answer: negative

Question: Used it in birdbath to keep water from being stagnant- put it in my dog's swimming pool - it's fun to watch and turns off when water dries out. I recommend this!
