If you have jack stands from Harbor Freight, you need to check to see if they're on this list.

That’s crazy. Fortunately with the Q, the only time I really need to lift on stands, is when doing the differential fluid or fuel filter. The 4th gen Maxima almost always requires jack to get to the oil filter.

I have the big reds...and craftsman somewhere. Both have lasted awhile. That said, I hate the idea of doing anything that involves having the jack be the only thing standing between me and the pavement. I use mainly for leverage purposes, not so much to support the vehicle.
