Query: Hard to apply and ineffective

I purchased this product because it was all natural. It works initially, but not more than a couple of hours. It needs to be reapplied throughout the day. I work in an air conditioned office and I can smell odor at the end of the day. I have also used it when I am at the gym and it definitely does not work.As in previous review, it is very sticky and you need to add a little bit of water before it can be applied otherwise it is too tough to apply. I have used less than 10 times and threw it away because it does not do the job. Do yourself a favor and buy the all natural crystal type deodorants.
