Well jww, you are not the only one there, i also have the same problem with MX271. I have worn it 3 sprays & refresh 3 sprays on my night out but let’s just say it didn’t turn out good…instead i end up getting my leg injured 
Check out my link for more info> Just telling you guys that i’m testing out MX271 tonight:)
Yes some reports here show that MX271 does not show any reaction whatsoever to people in their age 20’s. Zero And people under 30’s & over 60’s is only a little affected by it. But people in their 30’s & 40’s reacted much more to it. This is what i have read so far
