"The question that ought to have been but was not in the series of automatically generated questions about Easy Digging is, "How dumb were our questions overall?". What, for example, is an "Overall shopping experience"? That one I'd have given four question marks, and six "Huh's?".
I bought the stab planter. I haven't used it yet, but the first thing I did was look at it very carefully. The different seed cylinders, (there are six of them), should be terrific for corn, and, as it says on the tin, larger seeds. That they are rotating cylinders and not rotating wheels seems a plus in the direction of simplicity. The instructions are relatively clear and easy to follow, though I think the instructions to use the tab which delivers either one, two or three seeds might be mixed about. But as the instructions recommend, try the planter out on a brick and seed how many seeds come out. The body of the planter has, as they say, a side for seeds and a side to deliver fertilizer. The latter in I believe, IIRC, 1/2 tsp., and then greater amounts. The plastic plate at the bottom of the 'plunger', and the plunger itself could be weak. (I don't think it would resist angled stresses.)
I haven't yet used it, correct. Though I've made some trial plunges, and the soil into which I tried was quite firm. I'd loosen the soil somewhat first
Delivery time really was five star, as is the tool, and the web site/sites. (Clothe's pins. Wow!)"
