Bests & Worsts Reviews from Amazon

Shame on me for not reading the reviews first! I never would have bought this. I had another one from a different manufacturer & loved it. This comes with no instructions. I had to read the reviews to figure out the batteries. There is a white disc on one side of it that I assumed was a button. But after reading the reviews I found out it was a "speaker." It's not really a speaker. I believe it's​ there to make the buyer think there's a button. It's cheaply made & isn't loud! Don't waste your money!
