Haven't had it long enough to see long-term effects, but the first use - no nasty smell, covered easily, left my hands and the cats' (we have two) hair soft. Cats didn't fight application like with other products.
Out of all the flea killers this product is safer. My cat does not foam at the mouth. It kills the fleas and ticks in a few minutes and leaves the cat's with a fresh smell and softness. I have been using this product over 20 years. It never failed my pets.
It helps to rid fleas fast as it states on the bottle.
It has a neutral scent and is not agitating to pet or human when appropriately used according to manufacture description.
