Review on Device Ultrasonic Adjustable Frequency Flashlight Rechargeable by Nicole Brown

This only got 4 stars because these devices really need a SWITCH instead of holding the mute button for 10 seconds to turn them off. Instead of turning it off, I leave it on all the time. It's rechargeable, making it easy. I haven't run out of juice on my first charge in 2 months of limited but significant use. What I love most about this item is the WARNING SOUND! It quickly becomes as effective as ultrasound when trained properly. I've had to change the frequency type a few times, but the beep is usually enough to get a few dogs' attention. I returned another item with a switch and additional effective distance for this item. I gave up about 10ft and a switch but it works so well I can't complain. It's small enough to be hidden in your hand. But it can work if you put it in your pocket. The clicker and the whistle are power-ups I haven't used yet. The light is ok but I haven't used it in the dark or to charge animals. It is exactly as described and I recommend it to many others.
