I really like the Tisserand Deodorants.
I have purchased all three (Rose Blend, Lavender Blend, Tea Tree) and my favorite by far is the Rose Blend. It is a fairly strong scent, so if you aren't a fan of strong scents it'd probably be best to go with the Lavender or Tea Tree. The Lavender one actually smells similar to Froot Loops in my opinion!
The negative is the price point. They are pretty over-priced, especially if you are ordering online. I have been lucky enough to find quite a few at Winners / Marshalls.
The effectiveness is pretty good, again keep in mind it is just a deodorant and not an anti-perspirant, so it will basically just help with any body odour.
