Query: Best shaker ever, does not leak!

I am very surprised to read all the reviews of this shaker leaking, it's quite the opposite. The top fits snug but most shakers in the past are hard to get apart when cold, this one easily comes off. The best part is the contents smoothly pour out unlike many I have had in the past that dribble out the spout.
