Perfect fit for Kobalt 21" corded electric mower

Blade is a perfect fit for 21" Kobalt electric mower. Price is a little high but it seems like about average quality for nowadays.

Not for Kobalt mowers.

Would Not Recommend

This blade will not fit on the 80 volt Kobalt 21" mower. No problem with return. Exact replacement blade needed is impossible to find.

Lowe's is usually a good place to buy whatever.

Would Recommend

The blade is great, but not so much the effort in getting it. I will stop here because this might be an isolated incident; usually good, up to now.

Takes a while to get a simple item.

Would Not Recommend

I like the mower and the blades but this will be my last Kobalt or anything Lowe's branded.
