this is my 2nd order of my pet peed and it does everything it says it does i have 5 dogs 2 males that occasionally hike their leg in the past i tried everything and nothing worked i would get so stressed and actually followed my dogs around to make sure they didn't hike their leg the dogs and myself were a nervous wreck then i saw your advertisement on line and you guaranteed a refund so i went for it no more stress no more nervous wreck this product is the best everything you said is absolutely true and my dogs no longer go back to the spots they frequented the only time i notice i am going to have a problem is when my sister brings her 3 male dogs over and i can't monitor them because i am entertaining my sister! i always make sure i have plenty on hand and your flashlight is the best i can actually shine on every area of my carpet to see if there is any sign of urine this flashlight is a must no guessing where they might of peed or down on the carpet sniffing every square inch of carpet just shine light over carpet and you will know soon enough this is my first ever testimonial but i believe and trust in this product so much i just had to let anyone who reads this that if you purchase this product it will be one of the best investments you will ever make
