(-) The taste of Lemon Lime is kind of disgusting and incredibly sweet. Although this is very subjective but I would not even recommend something my worst competitor.
(-) Can not be opened as well.
(-) In 1 of 3 packages can be opened only with brute effort opening the mouth. This is while driving and even more so during the competition simply tiring and a no-go.
(-) Content can be (unfortunately) only partially emptied. 10-20% remain remaining. Either you give yourself more trouble or dispense with the rest.
(+/-) Einzelt not cheaper than in the drugstore at Amazon (but for Powerbar's fault)
(+) Very fast filling
As for the negative reviews, I made the Enegry gel by Multipower better experience.
