After seeing some of the ways to get the juice out of those 10ml bottles I thought I'd try this and it works great. Just a spare tube from the compressed air I use for computer cleaning. I cut it into 4 pieces and I've been using it for a couple of days now with no problems. The fit is a little tight on the juice bottle, but it stays in fine. Just insert in the tank and squeeze the bottle. The price sure is right and it does the job.
