Review on Rise And Grind Shaker Bottle - 16 oz, BPA Free, Black with Lid Mixing Technology by Mike Robinson

I only received this item today and it came in a box with no foam protection, just plastic wrap (no bubble wrap). This shaker bottle is sized in ounces (1oz - 16oz) on one side and ml (50ml - 500ml) on the other side. I tested this "sealed" water shaker and it passed! The only negatives I've found are that the dimensions are engraved a little thinly on the sides, which I think can wear off over time, and the lid is a bit difficult to open (which is good, because that's probably why it's so airtight). Overall, I love this shaker and definitely recommend it!
