I bought the 1, 2, 3 and 5 gallon ones. The sizes calculation are a bit of a stretch. If you fill the soil all the way to the top then they'll pass, but just expect slightly less than the actual size. It's a good price and looks like good quality so I have no complains.

For my hot climate it dried it very fast and needs watering every day, because of this I add more compost in them along with the potting mix, or double stacking the bags to reduce drainage. (Some people are against compost in containers, but imo this is less of a problem in grow bags because they drain so fast in hot climate).

The roots grow really well in them. I use 1 - 2 gallon containers to grow microdwarf, 3 gallons for determined dwarf tomatoes, and 5 gallons for indetermined dwarfs, cherry tomatoes or full sized tomatoes but top them off and limit the plant to one or two stem.

Nice sturdy bags, handles on the 7 gal bag had no problem holding up under the weight of a full bag. I'm using these bags to try and stop from introducing bacteria or diseased soil. I am putting them on a hand made square frame made of 2 x 4 a little bigger then the bag and covering with a wire mesh strong enough to support the weight, this way the bags can have good drainage and air prune better then being on a hard flat surface.

I was hesitant to purchase because I've never strayed far from smart pots, the price was the deciding factor. I will never purchase smart pots again! Love these things.

I cannot say enough good things about these garden pots. I've used some by another manufacturer in the past and had mixed results. My mother and I wanted to grow potatoes this year but putting things in the ground is just too hard at our ages (58 and 84) so everything is in containers or raised beds.

I used a mixture of miracle grow potting soil and some composted garden soil that we let sit over the winter. Probably about 50-50. I set each of the bags on four flat landscaping bricks because I thought that would make them sit more evenly. My mom planted her potatoes in 3 of the bags a few weeks after St. Patrick's Day. I planted 2 eggplant in the last 2 bags a few weeks after that. It was warm here in eastern Pennsylvania so I pushed the season.

Both the potatoes and eggplant grew beautifully. We have already already harvested all of the potatoes and have replanted the pots with more potatoes to try for a 2nd season. So far, they are growing well. We have been harvesting large fist size eggplants at a rate of about 1 or 2 a week. We planted a variety grown particularly for containers.

These bags dramatically increased the real estate of my garden. It took almost no preparation and, as it looks now, they will be in great shape for use next year. I do plan to empty them out come fall and keep them in the basement. I have attached a few photos.

UPDATE: April 30, 2017
My plans to empty out the bags and put them away for the winter went awry. I just never got to it. They all stayed outside. I turned them over about 3 weeks ago and am happy to report that they survived the season intact. I have refilled all of them with "energized" soil. (I took last year's stuff and added some manure, hay, and water. I let everything sit under a tarp in the sun for a few weeks and then shoveled it back in the fabric pots.) The soil is not ideal but, sometimes, situations dictate shortcuts. I've planted 2 eggplants and am getting ready to do the potatoes in the next week or so. The bags show no sign of wear and tear. Another big thumbs up!

So far I love my pots. I am not allowed to have an actual garden where I live so I bought two sets of the pots and my plants are doing well. I have tomatoes, peppers, eggplant, basil, squash, and zucchini. The plants are growing well, and I really like the fact that since I am trying to sell my house, if I end up moving I can take my little garden with me!!
