Is PetArmor a good flea treatment?

5.0 out of 5 stars Best value! Dawn to kill them, this to keep them off! I have not found a product that works this well for the cost. Even when we have had a flea problem, after washing our dogs off with Dawn (which seriously kills the fleas on them), this has kept the fleas off.
