Ex Input:
I tried the Frooties mBerry and the effect lasted one hour for me. I purchased this version since it had excellent reviews and was a slightly higher price.  This version lasted only ten minutes. I tried tablets out of three different packages from three different batches to make sure it was not a faulty batch. The results from each test was the same.  I would not suggest this version of the product, other tablet versions may be more effective but would suggest actual berries.
