I've used Whistle for over 5 years.
I've had both the original Whistle, Whistle 2 and have just ordered Whistle 3. We have had great results using Whistle, since Lucy, our Mini-Aussie likes to wonder around. The only problem with the Whistle was keeping it charged, since the other two had a base/transmission station and that is where you attached the Whistle 2 transmitter to recharge it. While traveling we had to bring the base station for recharging and it was a 110 Volt charger. With the new W-3 we can recharge while in a vehicle and we don't have to worry about a base station. Excellent design and the company is very customer oriented.
