Well, I went ahead, bit the bullet, and bought one of these things. I obviously don't have any product to taste test yet, but so long as it works, I guess it's not going to be a purchase I regret, though not something I am going to brag about, either.
On the upside, it does have a fairly stylish look, it's efficient, it's pretty much idiot-proof, and once I took a look at some of the pods, I figured an easy way to MacGuyver my own pods (for a lot less money) that contain whatever the heck I want them to contain. Whether my idea will ultimately work or not remains to be seen. I'm attempting to grow chives with my jimmy-rigged "pod".
On the downside, it's a bit bulky--I actually don't even have mine in my kitchen; I've put it on my breakfast bar in my dining room. The pods (if you choose to buy them) are expensive, and some of their choices are head scratchers (Dill? Seriously? Dill will take over your entire house if you let it; I don't even want to think what it will do in a limited space environment like that). And the price is offputting a bit--but hey, it's only money in the end, right? Not like one can't just go and get more.
Could someone make something like this on their own with grow bulbs and installing fixtures and what not? Yeah, sure. I could also break down the wall separating our library from my den and then transform my den into the ultimate man-space. Doesn't mean I want to (OK, I want to, but it doesn't mean I have the motivation, inclination, time or energy to do that much work--and the Lady of the House would not only kill me, she would start nagging me to fix other things around the house again since I was feeling so "handy").
Conclusion: It's not going to be the proudest purchase you ever make, but you're not gonna kick yourself over it like you would if you bought Chef Tony's Abomination Blades, the pasta express or whatever other ridiculous infomercial product of the week is begging for your dollar.
