G Fuel Winter White Shaker Bottle, Drink Mixer for Pre Workout, Protein Shake, Smoothie Mix, Meal Replacement Shakes, Energy Powder and More, Blender Cup, Portable Safe, BPA Free Plastic - 16 oz

Came in perfect condition and the lid/cap is very sturdy. I do hold the lid with my finger while shaking the bottle but I could trust it to not open during the shaking process. This is not common, my previous gfuel shaker from a collaboration had a very loose cap. Be warned about product quality consistency. Small and fit in all cup holders, easy to clean and maintain, decent amount of volume, and light. The "filter" they have is a separate piece from the entire lid so there are 3 parts in total, body, filter, lid/cap(it is removable).

This is a cool product and the black colour is perfect! it’s got a really nice, sleek looking quality and has a good mixability, with a few minor leaks through the top. It’s really durable and easy to clean. It functions perfectly for the Gfuel energy mixture.

I love the form factor of this significantly better than the blender bottles because it's more squished down and a little wider while maintaining the standard 500 ml, which means it feels more stable and is a lot harder to accidentally knock over. It also just generally feels better in the hand that way I feel. The only problem I've noticed is at the hinge of the mouthpiece it tends to flick water around a tiny bit when I shake it but it's not super major and hasn't been too huge a problem. Cleaning isn't super hard, if you wanna really get in all the bits I usually put a tiny drop of dish soap inside and fill it about halfway with warm-hot water and close it all up and shake it and then drain it all out the mouth. After that you can really get in and scrub the rest of it but that should get rid of the stuff you'll probably miss. For the cost and the fact I use it every day I'd say it's well worth getting instead of wasting water bottles.

Just the right size for my morning pick up. You really need to put the lid on tight. It does not have a gasket, so it will leak when shaken. I wish gfuel made their shakers with a handle clip. Makes it easier to tote around.

Classic G-Fuel shaker cup! Love it. Perfect size and great for the money. Love the built in "mixer" instead of using a ball.

Feel super sturdy and does what its supposed to, haven’t noticed any leaks so if it’s leaking it might be a user error.

It feels good in the hand, does a good job mixing the G-FUEL with the water, but it does leak. Shaking for more than a second or two will cause the liquid inside to leak out the threads of the cap and onto your hand. Otherwise, it's a cup with a lid. I wouldn't recommend buying this.

Great for my G-Fuel works great. Cleans easy, perfect size, doesn’t feel cheap even though it was inexpensive
