[EX Q]: 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.
[EX A]: positive

[EX Q]: I received way more tops than bottles--some that made no sense, AND NO TOPS for the smallest bottles. It was kind of a disaster. I would not recommend ordering this product.
[EX A]: negative

[EX Q]: The day I started taking this I encountered painful gastrointestinal symptoms, but kept taking it, thinking it was a coincidence. After 4 days of discomfort concluding with a missed day of work, I finally stopped and switched to the other product marketed to this demographic, and the symptoms went away. I don't know if it was just coincidence or if this product had the opposite effect intended on me, but one other commenter said the same thing, so I wonder if one of the ingredients is problematic for some people. I'd like to experiment to find out if it was just coincidence, but I don't want to feel that way again and will stay with the competition.
[EX A]:
negative
