I purchased this for myself for Christmas. Love it. Don't believe those complainers that it's too bright and noisy. Where did they put--on their nightstand? Mine is in the kitchen and I don't usually sleep there. It is bright--you need light to grow plants. There is a very slight hum and water sound. Unless you are sitting right next to it listening for something to complain about it won't disturbe you.
I planted the herbs and they are growing nicely, especially the basil plants. I ahve had to raise the lights three times already. Instructions seem to cover everything--especially how to harvest your crop. In the box is a coupon to purchase more seeds for something like $4.99.
I purchased at Bed Bath & Beyond using their 20% off coupon. Even if the coupon is expired they will honor the discount. Also, if you purchase first, you can come back with your sales receipt and the coupon and they will give you the 20% off. Great store!
You can also make your own "pods" and grow whatever small plants you want. I'm going to try cherry tomatoes next.
