Buy the least expensive---you will be replacing a lot of them.

One way to save money is to alternate sides, instead of lining each side.

I have used the first and fourth snow stakes.
The circled reflectors ars not as tall as the white orange pole stakes , off only by a few inches. I guess it depends on who manufacturers them.
The circled reflectors shaft splintered over time . These tiny slivers are nasty.
I have a 1200 foot drive way.
I used the first circled reflectors to stake the utility box and stream. I used the orange and yellow stakes to border the drive leaving space for the tractor to pass as we hauled the snow.
I bought a box of 200 stakes off the internet and a few break each year by the UPS truck or they snap as I pull them out at the end of the season.

thanks! are the pole type reflectors (orange & yellow in photo) easy to push into the ground? if its snowing, is it too late to push the plastic into the frozen ground?

Once the ground freezes it is very difficult to insert the thin orange snow stakes. They do not advance and end bending as you try to force them in.

I paid less buying them off the internet then Home Depot prices.
OHio..... it takes a few days of solid freezing temps for the ground to freeze. We have had two snow falls , a few nights of 25 degree temps and the days in the low 50's. I planted bulbs yesterday with no issue.
Plan on getting the drive staked this week.
I used two poles to denote rocks, or an old telephone box. It sucks hitting this with the tractor.
