GREAT!! I figured you would have it by now. Did you get the needle-nose filler. If you did, push the needle between the inside of the carto wall & the filler & allow a few drops to get down to the bottom. Go around the carto & keep doing this. If you don't have the needle-nose you can fill right from the bottle, just tilt the carto towards you at about a 45 degree angle & drip some drops in again going towards the inside wall of the carto while its soaking into the filler, again turning the carto as you're doing this. DON'T LET ANY JUICE GO DOWN THE CENTER TUBE!!!! Let me know if you've done this yet.......BTW...this carto should take approx 60 drops, not sure & stand to be corrected.......
