Just ordered my mflb off of Amazon for £65, should be here by Friday, gives me a chance to go on a mini T break of... One day is the mflb really worth it? Also, I have a question when I'm hitting it, after I've held the battery in for 5 seconds before the hit, do I keep the batery in? Or release it and then take the hit? Thanks.
Keep the battery in until your lungs are almost full... Pop the battery out and take a half second draw to clear the remaining vapor i the stem and chamber.
