I had a coupon for a free stick of Secret Clinical strength deodorant, which is why I first tried it. I will say I have bought no other brand since. It is a bit on the expensive side for deodorant but it is worth it, in my opinion.
It is recommended to put it on at night when you're not perspiring for it to be fully effective. I do this and even after I shower the next day I can still smell the deodorant. The scent lasts for a long time, which is something that I need. It does not mask the odor, it prevents the odor altogether. You should try different clicks of the deodorant to see how much works best for you. Some people may need more while others need less. I use 2 clicks and it works great!
I only had one issue with this and it wasn't the deodorant itself it was the container that it's in. I had bought one brand new from wal-mart and the first time I clicked it broke. I contacted Secret and they replaced it for me so all was not lost. I would recommend this to anyone, it is a great product.
