Works like a charm. Looking for an extra 5-10 minutes this product is for you.it doesn't workDoesn't work!first i did n't ask for any strength. second this thing does n't give any strength. any way i was looking for just delay,and this thing is not even for delay. first time i use it, i spray 3 times and wait for 15 minutes nothing happened. second time i use it, i spray 5 times and i wait for 15 minutes also nothing happened. i gave it one star to allow me to write my comment.Practice make perfect. Once the right spot is found and the right amount is used it worked great. But, it took a few times to perfect it but now...omg!
