Ive been using boom for years and love it. For the first purchase I recommend getting the kit that has the cotton strips and applicator, after that just get the jar of remover. I do not have a microwave so warm it in water on the stove (set on low) the jar is glass so won't melt. It is a little thicker than some removers but really grabs the hair. You CANNOT use it without warming, it just won't spread. The clean up is so easy. You just fill the sink up with cold water, throw in the used strips and applicator then walk away, go do something else, take a shower to wash off the residue from hair removal. They will magically be free of hair and sugar wax when you come back. Just rinse and dry. Good for the environment too as you can re-use the strips forever. Plus no chemicals or nasty ingredients.
