Hey all. I have some experience with these also.
I had two of the speckly ones last weekend. they are very stromg, but not too bad. I had lots of initial rushes, then was pretty much charging and peaking like normal MDMA.... then as the night progressed, and I took my second.. I kept peaking.. and was very energised and huggy and chatty.. but EVERY TIME I closed my eyes... I was lost in another world, my very first visuals on a pill.. they were so intense, someone had to shake me to get my eyes to open again. Then, even later in the night, I had open eye visuals, lights flickering, lightning bolts and patters.... all the while... still peaking and feeling all nice like you do from MDMA.... they peak lasted all night really... and didnt come down till 7AM... I had no bad comedown... then again.. I never do... and I was in good spirits afterwards.. and went out the next night..
NOTE: A friend had her first ever pill... in halves... a flat pink omega, not the speckled one... She was fine for an hour... then spewed, and spewed 4 times, then was basically a mess the whole night, could not talk, stand, nothing. And she remembers nothing. I think her tolerance was NILL, coz she had half a batman the nextnight, and still was wrecked for half an hour.. before she started to like it. Strange!
