Review on Xflyee Electronic Whistle: USB Rechargeable, Adjustable Tones For Referees, Coaches & Teachers | Perfect For Outdoor Activities, Boating, And Safety by Paul Mac

This is awesome! I've been reffing soccer for almost a year now, and with Covid, using regular whistles was problematic. I was initially hesitant to get one of these electric whistles, but it's actually really really great. The one thing you really need to be careful of though is where it's pointed on the field when you use it. I could see this easily damaging someone's hearing if you accidentally blasted it near their ear. Great for overall use, but just be aware of it and don't get in the habit of blasting it at a higher level. A great option over conventional whistles
