I originally got them last spring. They work perfectly for what is needed. And if you Square Foot Garden, 5 of these small ones is perfect for a 4x4 bed. It definitely made last season so much easier to manage in regards to watering and irrigation. I'd just go out twice a week, or 3x if it's really hot to refill. My plants definitely benefited last year. So I'm looking forward to season 2. Review: They seem good - These came up on my search when I was looking for more ollas for this season. They were cheaper than the ones I bought last year, so I bought one. It seems good and I will be buying a few more soon. They seem to be a little lighter than the ones I have already, maybe thinner clay? I will just be a little more careful when handling them. They have the silicone lids that I liked on my other ones but these were half the price of those. ## Features - Efficient Olla Watering System: Dive into the seamless integration of the olla pot or oya watering pot alternative.
