Ice Shaker Stainless Steel Insulated Water Bottle Protein Mixing Cup (Black)

Very durable, as long as the seal in the lid doesn’t slip or get wore down, I like it very leeakproof

Very durable, as long as the seal in the lid doesn’t slip or get wore down, very much leakproof. My toddler throwing it on the hardwood multiple times every time I use it, tests out the durability of this cup. When used as just a water bottle for work, a full shaker of just ice water will hold ice for a 6 hour period, or 4 refills. Haven’t tried hot beverages, but I have high hopes since it’s so well with cold beverages. I will be purchasing a tumbler version of this cup in the near future.

Fantastic product. Very solid and robust. I am looking to buy actually now a second one.

Excelente, de verdad cumple con lo que promete

Seriously a high quality product. I purchased this for my bestie and he uses protein shakers in our work vehicle for 10hr shifts and with the hot weather, thought this would be great. It is an amazing product, with no leaking or issues, and keeps drinks cold for hours, even in the work car in 40 degree heat. I ended up buying myself and my husband one each too.

Great design, however there are some tiny gaps in the lid that causes unmixed powder to get stuck. Also the base of the inside should be rounded, for better cleanability. X2 things to fix, then best shaker bottle ever!
