Unit works well. Door shuts tight. Bottom loader is easy to load. BUT I had 5 gallon  bottles from Home Hardware.  Good thing it was a bottom loader we just sit the tube with large metal cap into jug, it is loose but works at drawing water up. No leaks anywhere. I paid $20.00 for the jugs (each for 3 ) and didn't want to put them in blue boxes. So am thankful I can use the 5 gallon bottles I have. I think Vitapur has their own. Rubber cap was bought but Home Hardware bottle opening too small to fit.  It was to arrive Aug. 10, then Aug. 4 then email said Aug. 2nd . . . I ordered it online August 1, 2017, One day free delivery as it was over $75.00. The unit was not on sale but it was still lest expensive than local stores by about $40.00.
