Fast service, but a couple of things knock off some points. First, and this is not usually a problem for me, being a flavor-chaser and a lover of dessert flavors, the juice is too sweet for me. It is good occasionally, but I couldn't do them all the time (I tried 5 different flavors). Secondly, the small bottle tips are too blunt to fit into tight fill spaces. And lastly, the small bottles are just plain hard to squeeze. I had to use spring clamps to fill my tanks, my hands couldn't take it. To be fair, I have only had the sampler (which is awesome that they provide!) which is small bottles, I haven't had any larger bottles which may be different.
