I am rating this a 7 out of 10 only because I wish the product wasn't harmful to the environment. It works so well and there is never that dirty toilet brush sitting in the bathroom. Performance Performance wise, this thing is easy to use and cleans wonderfully. You just attach the refill to the wand, wet the refill in the toilet and then scrub all while only touching the top part of the handle. I have been using this product since for at least six years now. I do use the refill on more than one toilet. I usually clean 2-3 toilets with one refill depending on how much use each toilet got. Scent There really is no scent with this product which is nice. No fragrance or chemical smell that I have noticed at least it's not strong enough for me to smell.
