Bests & Worsts Reviews from Amazon

I am new to shakers. These cheap shakers had bad reviews, the expensive shakers had bad reviews as well. It was hard to choose 2 shakers so I ended up buying one of each. Some reviews are very deceiving for the simple fact that they don't know how to shut the lid correctly. I'm my video I show two bad review demonstrations showing that they don't happen when you properly use the shaker. Knowing what I know now I would bought 2 of these for 20 bucks then spending 30 dollars for 2. Do products come out defective? Absolutely but the two examples I showed of people giving it bad reviews is obviously because they don't know how to use it and decieve future customers. Obviously my shaker is new but I wanted to make this clear from now in case it helps with the decision of people buying it or not. I will update my review when I put to to some good use to see if it still holds.
