[EX Q]: I absolutely like it The brain booster influences well on my alertness and memory. I feel much more clear after half an hour of taking them. I think that they even improve my critical thinking.
[EX A]: positive

[EX Q]: My twin two year olds love detailed toys where they have to put things together and this was perfect! It entertains them and they can work on their coordination with smaller objects. Very easy to use. They try to stack them all in a straight line and have a blast seeing how high they can get
[EX A]: positive

[EX Q]: This is the most difficult electric can opener I've ever had. Actually, none of the other can openers I've had over the years have been difficult. This one? I tossed it after a month. Didn't even want to go through the hassle of returning it.
[EX A]:
negative
