Caffeine Energy Bracelet by Perk | 4-Hour Coffee Energy Shots Provide Focus Without the Crash | 30 Day Supply

The caffeine pad works (kind of). But the bracelet cannot keep the pad in contact with the skin sufficiently - either too tight or too loose. So I place two pads (to get enough caffeine to make a difference) on my skin and use a sticky tape to hold them in place.

I mean, after two patches in one day I'm feeling better, but the product doesn't work for me due to my caffeine intake.Low caffeine intake (20-60 mg) this product should work for youHigh Caffeine intake (60+ mg) this product is definitely not for you

I love this product. I used to work nights and this gave me the boost I needed at 3 in the morning. I think they work great

This product did not work for me. I used it multiple times and felt no effect. One time I fell asleep wearing the bracelet. Buy if for your self and see.

It did not work at all.

Better than 5-hour energy. Gets you going, and allows you to keep going for about 4 hrs.But I want to buy just the refill since I already have the bracelet.

Not enough caffeine
