It is really hard to remember since its been some time since I have read all that, but… I never remember reading a bad review on either of them, and the experienced users raved about them. I’m pretty sure I remember reading MX150 as being very consistant at low dosage. It had a flirty attraction, high comfort level, low resistance, and highly seductive with a cool pua type of self effect. I could be wrong. I might go back and do a little research to see if I my memory is any good.
