Love this shaker and a massive improvement on the previous shaker - the steel design makes the shaker more durable and unique while the cap system reduces the amount of spillage from previous shaker - would highly recommend and definitely worth the expense

Looks great but cap that fits in the spout snaps inside the spout.  Unfortunate really as looks really good

I have had a few shakers that I have used but this is hands down the best one. It mixes the protein, BCAA's, Creatine and Citroline perfectly wether its with water or milk and very rarely do you get any lumps because the angled blades in the lid mx everything perfectly. It also keeps it very cold for longer. Five Stars on this design :0) 

Very good product, no odour like plastic shakers and better for the environment! Keeps content cool and easier to clean than the plastic shakers. plus, the seal is great, have had no issues with the seal and have been using this product for a few months now! Overall best shaker on the market!

Unreal and is so good at keeping it cool. Highly recommend 

This shaker is good. It doesn't leak and design is good.

I read various reviews claiming this shaker was leaky but I have been pleasantly surprised with how good it is. Super simple and quick to use, easy to clean than regular shakers and it just generally looks better than others too! Worth it!

Looks and feels great but not great at mixing protein powders 

I have tried various types of shakers until now, and I must say that this is the most comfortable. The fit of the top piece is perfect because it has a plastic wrap on the inside, which makes it impossible for any water to spill. I also found that it is the better choice to a plastic shaker since the formation of mold is reduced and, in case that you might forget to wash it out after having a protein shake, the smell will go away at once after washing it with a bit of dish soap. It keeps drink cold or hot for a long time, especially in winter, I can make a tea and keep it warm for over two hours. I would definitely recommend it to everyone, it is really the best choice you'll make!

This is a very well constructed product and I use it everyday super design easy to clean
