I have tried 3 differant brands this year due to the store running out and by the end I ended up making my own so that would be 4 and I saw deer with all I think it is just a matter of preferance per certain brands IMO they all poses the same basic ingrediants Distilled water, Baking soda and Hydrogin Poroxide I made mine by boiling my water with pine needles from my tree I sit in, and then added equall amounts of the water and Hydrogin Poroxide and 1C of Baking soda per 16oz of water. ps when mixing put in alerger conatiner and keep out side for a day sometime the baking soda mixed with the poroxide will bubble so Do Not Do it in a Closed container.and it worked great! I still saw deerand cost a fraction of the store bought stuff. Good luck
