I used to use china brush years ago and it worked great, too much applied had undesirable results but it worked. So far I have used this twice, it is slightly desensitizing but overall was quite poor. Might work for some but definitely not me.

Having used the original China Brush with great success this was a big disappointment. Despite applying 3 times it had zero effect. Save money - Don't buy

I usually find that delay stuff completely numbs you to the point where you don’t even enjoy the sex because you can’t feel it but this stuff is great. It did the job and I could still enjoy the sex! You hardly have to use any too so this bottle will last a while.
