Bests & Worsts Reviews from Amazon

I bought these whistles based on the good reviews. I did receive them on time and was pleased with the extra lanyard that came with it. I am disappointed that only one of them works. Paid for a pair and one is useless. UPDATE! I have changed my rating to 5 stars. Unexpectedly today I received two more whistles in the mail. Both work beautifully and super loud. I can only assume the seller read my review and took it upon themselves to make my order right. Excellent product and customer service. Thank you.
