Kickers 80 hour energy spray is one of the most affordable ways to get a boost of energy when you need it most. The package makes claims of no jitters, and no crash. I have been using this product for a week and haven't noticed a crash yet! It can cause jitters if you take to much though. Kickers is easy to use. You spray four squirts under your tounge, and wait 30 seconds before swallowing. You can increase, or decrease the dosage based on your desired level of energy. The best part is, it comes in a small pump bottle that fits in your purse. Each bottle cost $4.99 and has 20 dosages ( four squirts per dose) = 80 hours of energy. The bad thing about this spray is the taste! It takes some time to get used to the bitter after taste, but worth it. Just make sure you have something to drink on stand by. You can find this product next to energy shots, and pills. I recommend anyone who needs a little "get up and go" to try this product out.
