I was not getting alot of vapor or throat hit on my 401 atomisers. I have been using the same 2 hole atomisers since feb. So i decided to examined my 2 hole ones to see the difference in them. what i found is that they where pushed up in the tube alot and making it able to be closer to the battery which was giving them more power to produce more vapor. So decided to gently but firmly push my 4 hole atomisers up alittle bit into the tube until i felt resistance. then i decided to try them out after this slight modification, and to my suprpirse they produce just as much vapor as my 2 hole ones. I dont sugeest this if yours are working fine. i also just drip 100 percent of the time it probably will not work well with carts because they will be to far up to come in contact the the material. I was wondering if anyone else has done this. For anyone trying to this I am not liable for a dead atomiser lol. Use at your own risk
