Where are you seeing those? Dell's refurbished systems from their direct outlet have a Dell warranty, same as new (1 or 3 years, typically, depending on the model.) In my experience, the quality control is better than new ones. The price is a lot better, so as long as you can find a configuration you like, there's really no reason NOT to buy there unless you need a model that hasn't shown up on Outlet yet or you get an extraordinarily good sale (my present daily driver, a Latitude 7400 2-in-1 was new from the small business site, and cheaper than the outlet ones with a similar config, so it can happen.)

i have seen some dell refurbished computers selling as scratch and dent condition. how bad are they? and the refurbished ones, do they have new batteries? More on reddit.com

If they offer a warranty, get it. If not, understand you may be throwing it away sooner than you intend. More on reddit.com

I've bought from dell refurbished many times, usually desktops and they've all been great. I bought a few laptops as well. 1 had a bad battery which I noticed after the 100 day limit because I always keep it plugged in. Sent them an email, got a reply on 2nd day, then they sent a replacement battery. It was the wrong one, sent email, they sent correct one next day, told me to keep the wrong one. It's been fine since then. More on reddit.com
