The product itself is not great, but functions at a basic level. As stated in older reviews, there are cheap tack welds holding the handle on, and there are rough burrs on the core tip.After using it once, I will say that if you have any rocks in your yard/sample area larger than the tip opening, you're better off with a clean shovel. Rocks bigger than about 1/2 inch will stop this tool in its tracks, and if you try to back it out slightly and go in at an angle, most of the sample falls out the

It collects a little bit of dirt, and then starts pushing dirt further into the ground. Works as expected. Should last forever! It does not have a good design.

Well built but needs attachments to drive into and to pull out of soil. I tried taking samples in my yard in damp soil 1 day after a rain. I had to used a hammer to drive it into the soil. I used the same hammer to knock it sideways to losen it enough to pull up with my hands. I would recommend you buy one that's like a shovel.
