Tango vs Salsa

Someone once told me the Salsa is more effective, so that's the one I bought.

I have both and personally like them equally. The only difference besides shape is that the vibrations do dull slightly when you apply pressure with the Tango but it's not a BIG change.

I actually did not like Tango i own

well, if you like pressure, go with the salsa!

I find both to be about the same aside from the tip's design. I'd say to go with the one you like more.

Another thing is that both rotate on their axis when vibrating, so if your fingers are slippery the Tango won't stay in the position you want it to.
