Review on LOVE2PET® Ultrasonic Flea Tick Shield by Sam Lund

Worked, got rid of the sudden infection. Only the dogs were treated, and one decided to hunt and brought a lot. Spread to 2nd dog and I couldn't 'treat' her without poisoning her. I read about it, did a search and found it here so I bought 2 with fast shipping. (1) one day, that's all it took. Cons: died less time than stated in the description. Making it so you can change batteries would be great! the same concept as a plug-in ultrasonic or electromagnetic pest repeller that works!
