First off, the item that was sent was wrong one! Should have been i5, 16 gig mem,240 new ssd,wifi. received, i7, 8gig mem, 240 gig ssd, no wifi………………. you say, that's not so bad, I thought so too, at first. Then I thought what was more important to me...…...and 16 gig mem, and wifi. So, the 240 ssd was great ,I would have been ok with the i5 also, the i7, ican live with,no problem, of course. Windows 10 pro was pre installed /w/digital liscense,they didn't tell that. However, it did install easily, but had hours of updates to do, Ido mean hours. Windows works fine.Paper that came with unit gave wrong email address for customer service, used phone # instead, was speaking to someone in asia somewhere,coudld hardly hear them as well as understand the broken English, after many tries finally got someone I could understand, Huge hassle. Explained the problem of the mem, and wifi, had to take pics of computer get new email address and send pics to prove only 8 gig installed, asked to be sent 8 more gig of mem as well as wifi dongle, since this was all Their mistake, and to please send it overnight so I could get on with life. Did that happen? No, of course not. After much, make that too much, back and fourth they finally agreed to send more mem and wifi dongle, and of course, not overnight, so I wait another week, to clear up their mistake. So,having said all that, I would say the cs dept. leaves a lot to be desired.I will say the unit arrived in good shape and was clean inside and out, looked like a new computer. It is fast, quiet, and was well packaged. The keyboard and mouse were junk,but worked. If, the mem & wifi dongle get here and are good then I'll be a bit happier, the built-in wifi that's missing,leaves me cold about this refurbisher  who sent the wrong unit in the first place. They have tried to make up for it, I'll give them that, but in the end it's not  good way to do business.Like so many before me have said, it's a toss up and unless you are willing to go to battle to get what you paid for, go another direction...……...build your own!
