EFOBO Electronic Whistle for Coaches, Handheld Lound Electric Whistle with Lanyard and Three Tone for Volleyball, Soccer Referee, P.E. Teacher, Police,Outdoor Camping, Self Defense Emergency (Black)

Nice size, comfortable to use, but not as loud as listed.

I purchased this whistle as an alternative to the standard whistle I was using to bring my students in from recess. I was looking for something I didn't have to blow into (because COVID), and this whistle did NOT disappoint! It is so easy to use. All you have to do is push a button and it sounds exactly like you are blowing a whistle. It's nice and loud and has three different pitches to choose from. It also has an off switch so you don't accidentally push the button in your pocket and set the whistle off. It comes with a cord so you can hang the whistle around your neck, or you can attach the ring to a teacher badge/lanyard.This is possibly my favorite purchase this year. I highly recommend it for anyone that has to use a whistle!

Did what it needed to do. I wish it were louder, but in an empty gym for volleyball with no spectators it worked well.I worked more than 15 matches as R1 and another 14 as R2 and didn't need to change batteries at all.

I was impressed at how load this whistle blew. If lost this would definitely be a life saving tool. It gave me piece of mind when during hunting season. It fits in the palm of my hand and it's light weight. It also has a lynard that I could wear it around my neck. Great tool to have on hand.

I was very disappointed that after a week of using this it stopped working. Waste of money. I wanted something more sanitary to use than a regular whistle. I work with little ones that are always curious about things and touching my lanyard. I thought this would do the trick. It worked wonderfully but for under a week. I don’t recommend this, save your money.
