This edging works great if you want a simple, grass-mulch barrier to define the boundary of a bed. Some reviews ding this product because there aren't enough spikes. Those people are doing it wrong. How many anchors depends on your situation. Buy landscape staples to suit your application. The anchor tabs on this edging has little notches for the staples to fit. The notches are right next to the vertical barrier, so the barrier is anchored better and stays more vertical. The 11 gauge staples are the heaviest and galvanized resists rust. I used 6 inch staples. If you are curving the barrier, use a staple every other tab. For straight runs, a staple every 4 tabs works great. Use the spikes if you hit a rock you can't get through with the staple. The spike blasts through or shifts small rocks. I used a spike to start a run of edging, or if I had a junction where two pieces of edging butt together.
As for most things, good prep work improves the result. The edging lays best on flat dirt. If you have an existing bed, hoe back the mulch a couple inches to expose dirt. If you are putting in a new bed, I'd hoe all the grass out of the edging path first.
