Not sure if this happened to any of you and was very surprised when it happened to me as I assumed those ejuice bottles were one solid piece. Since they are so damn hard to squeeze out I have been using: I find them much easier to fill up tank/clearomizer/cartomizer/etc. At any rate I was filling one of those up and squeezing very hard on ejuice bottle for 4-5 minutes while reclining on chair. Next thing I know the ejuice bottle busts open and I have about 30ml of ejuice on my shirt and hands. Apparently the ejuice bottles are actually two pieces the bottle and a snap on cap with a the dispenser nozzle. Just to make my self clear I was filling the bottle with image above from store botten ejuice bottle. I may have been being too impatient or squeezing to hard. But really, why do they have to make those holes so small that you have to squeeze with 10 pounds of force to get anything out of them. I'm lucky it was a night time juice that was only 4 mg/ml. I normally do 24 mg/ml but decided to try lower dosage at night. I washed up right away and have learned my lesson that when filling take your time and don't squeeze so damn hard that the top busts off. But still wonder why the holes or so damn small that it takes me 5 mins of squeezing really hard to fill up a 10 ml container.
