I've used multiple different version/brands of these things, because I absolutely love how easy it is to grow food hydroponically. This latest acquisition is a decent contender amongst the units out there. I might not recommend it for a first time user, because it does assume some knowledge on how to use them that aren't very clearly outlined in the instruction packet. Also, there are some glaring omissions in the overall experience, and I will list those out first: 1. The instructions tell you to put the A/B crystals together and mix them in the \"A/B bottle\" with water, but in fact there is no A/B bottle provided, only the two separate bottles of A granules and B granules. This wouldn't be a problem, except that they don't tell you what volume of water to use, and unless you want to guess or use some other solution you already have, you're out of luck. 2. There were only 11 plastic germination caps, so one of my plants shall be uncovered during germination. 3. It says in the instructions to turn off the light until germination, but I clicked and read and clicked and couldn't figure out a way to turn the light off without doing a factory reset; and even then, once you turn the unit off and back on, the light comes back on. I am also not really sure how to toggle between the \"germination\" and \"grow\" lights, I'm hoping there is some sign later once they start to grow (there are two different buttons that seem to do the same exact thing). But not having that ability is frustrating, and it's not outlined in the directions. Aside from those nits, the supplies that come with it seem high quality and similar to other units, and they are easy to use. The water add opening is quite handy right in front, and they've supplied a funnel to use for less spilling. There is a raised water height indicator, a nice addition that is more obvious and easier to read than most units I've tried. It has an LCD screen that allows you to change some settings and see what's c
