Hey ppl! I am new around here, so hello! Now I have a little question, I normally use retention+ or nsi attract. But been looking it odour free liquid. Just wondering does any use it? Is it as good as the ones I normally use? What is the best one? And if it is good, why are there still smelly liquids out there? Surely if it was as good, all liquid would be odour free? Hope someone can help me out here.
