Too cheap to be a quality part.
I have used denso 02 sensors with no problems.
Denso upstream, not that much more.

Denso down stream sensors

Do you have codes? Down stream sensors rarely fail. I'd buy quality upstream sensors and leave the down stream. If the front 02 sensors have been bad for a while, the cat may already be bad, and the downstream sensors are fine , just the cat isn't.
Ditto the above although you could also get them from Rockauto.com. Might be slightly cheaper with the 5% off code and especially if you have other minor items to add to the order.
I used Denso's in a Ford Taurus, never changed the downstream ones and the car had over 200k on the originals when I got rid of it. Technically it's a little more money because they're about $25 each instead of $15 each for 4 of them, but if you just get 2, it's still cheaper than $60 for 4. But yeah, I'd rather get a name brand part. I think my Denso's even came with a tube of lube.
