SignoraWare Shake n Shake Stainless Steel Protein Shaker Bottle for Pre-Post Workout | Water Bottle | With Blending Wheel and Whisking Wheel | Leakproof with Knob (650ml | Silver | Set 1)

يعني كويس اهم شي ما يسرب

Great Shaker it is also leakage proof and the quality is really good , it is really easy to use and clean using this from 2weeks and feels good , I am giving 4 stars because of the plastic lid if it was steel than it would have been a 5

The shaker does mix well and looks good but still leaks a bit, so the cap could be improved.

1. Beware while using hot liquids, When hot milk is inside the shaker, it opens throwing the contents out while shaking. I lost a scoop of protein as it opened mid shaking, poring the contents all over the place. I think the problem is only with hot fluids, as it is air tight inside, the pressure builds up inside, throwing the cap out, while shaking. So far only way is to hold the cap while shaking. Resolution: hold cap while shaking. 2. Steel container burns hand while hot liquids is inside the container. Resolution : Give some padding on steel body while holding. Singnoraware should have provided a simple rubber grip on the steel body so that we don't burn out hand. It would have solved the problem. 3. Noice while shaking. Since it's steel body with steel spring it makes noice while shaking. It might not be a big problem. Resolution: Tolerate the noise. Otherwise shaker is good with open mouth easy to clean. Got it delivered in good condition, with spring ball and plastic blocker.

Though the product is decent, I found the quality control and checks and balances pretty poor. Though the package was sealed the steel shaker spring was missing which is mentioned on the product page. This is unacceptable and casual on company's part. Pretty disappointed.
