🔋 Unleash the Energy: GFuel Black Out Shaker Cup for Game-Changing Performance Review

My son bought this after much research on different shakers. It was a great long lasting shaker. NO LEAK! He's doing his job. Easy and uncomplicated. Easy to clean

I don't understand how a shaker can be designed with such a fundamental flaw. The mug is designed to shake liquids without spilling them all over the place, but here's what happens when you shake this mug!

At first it did not leak, but now it leaks a little (where the upper screws are). According to my estimates, that was enough for about ten applications. Water because I used it at work and don't remember ever dropping it. So there's no reason it's already leaking. maybe if you just don't shake it.

Works well but after several uses and cleaning it started leaking somewhere between the bottle and the screw cap, I can't figure out where. A good flow but spills a few drops when shaken. Otherwise, I am very satisfied

Not leaking at first but leaking a little now (where the top screws are). According to my estimates, that was enough for about ten applications. It's in cold water because I used it at work and I don't remember ever dropping it. So there's no reason it's already leaking. maybe if you just don't shake it.

Works as a shaker. There are no leaks yet. I will update this review if I run into any issues in the long run. The price is more expensive than the one on the gfuel website BUT they don't sell this version anymore. I don't mind a price hike either as I'm not from Southeast Asia and buying through Revain guarantees it will be delivered to me :) I've also seen a few reviews saying it's fake but I disagree . It looks solid, doesn't look like a fake, the printings on the mug are good and not faded.
