Review: I'm a referee and this electronic whistle enabled me to effectively call games earlier this year - Can't blow a whistle with a mask on. I guess you could, but it would be uncomfortable and inconvenient. This electronic whistle is rechargeable, which makes it much better than one with replaceable batteries (my opinion, obviously). It's loud enough to be effective, but maybe a tad bit less than my Fox40 at full blast. The other thing I like, something I didn't anticipate, is that it's actually faster to call infractions. So you have to be careful not to step on a game too quickly in case, for example, there's advantage and a call would unnecessarily disrupt a game. Not having to constantly bring a whistle to my mouth actually feels really good so I may keep using this as the masks slowly disappear and rules relax (fingers crossed). Quality is more than acceptable. This model also has three selectable trills and varying loudness settings, so it has some options you can play with. The light is cute but almost useless. Anyway, as electronic whistles go, this model seems to have the best mix of features. Plus, it's rechargeable and a charge lasts me many weekends. It hasn't failed me so far (I've used it off and on for 4 months). If you need one this model is worthy of your consideration. Review: Easy to Use, Loud Enough and Reasonably Priced - The electronic whistle was great just coming out of the box. It have enough of a charge to test it out before I fully charged it. Charging is the easiest of all the electronic whistles I reviewed; just plug the supplied charging cord into a USB port and the whistle and let it charge. Could not be easier. Took it to my swim chapter meeting to demonstrate it and they loved it. I can see more purchases in the future. It is very affordable compared with similar products. The really greatest feature is the user does not have to deal with replacing batteries, as there is nothing to replace. Most officials leave it plugged into there car USB port and let it charge there. It's in the car, so you can't forget it when you go to a meet. Comes with a carry pouch and a lasso so can put it around you neck or wrist. An official actually put his on a lanyard connected to his belt loop, so you use it and let it dangle from you belt loop. If you don't have a USB connection port to charge it up, a separate AC to USB charger can be purchased at a very reasonable price. Can't go wrong with this pick. ## Features - 👍【Hand Squeeze Button Whistle】Electronic Button whistle can avoid mouth contact, no need to take off your mask which is really helpfull at this particular time!

Will probably need to wear a mask getting back on the ice soon** A: Possibly depends on the size of the arena and the size of the crowd. **Q: Is this loud enough to keep coyotes away?** A: It's loud enough to get 200 student's attention in for recess so it's probably loud enough to keep a coyote away. **Q: Could I use this to ref a soccer game?** A: Yes, definitely loud for games. **Q: Does it come with a charger?** A: I don’t know. But there is a port that looks like a charger would ply into it to recharge. I have been using this whistle for over a year now and haven’t needed to recharge it. There is a large battery in it like a 3” long AA battery; not your typical battery. Sooty this doesn’t completely answer the question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I'm a referee and this electronic whistle enabled me to effectively call games earlier this year *by K***P on June 22, 2021* Can't blow a whistle with a mask on.
