Water bottle rant

gotta say how much I hate them. got a new 40 gallon aquarium and 4 little girls. this past Sunday, first water bottle completely leaked out because it wasn't vertical enough. second water bottle stopped dispensing water entirely. why is it so difficult to get a proper reliable water bottle!?!?

I've had gerbils on and off since I was 10, but consistently for the last 18 years or so. Still can't believe this problem has not been solved.
