Initial issues w/startup but overall awesome desktop computer!
Love this desktop computer! 4 stars b/c I had sm issue starting up the computer, screen was blue with "Just a moment" message for a few hours. I did a system reset & no issues since. Is in safe mode so if you want to download/use Non-Microsoft apps you'll need to turn safe mode off. This was easy to do as I got a prompt when I needed to download certain apps. Also it's such a nice looking computer!

Is it Touchable?
It says it's touch screen when I touch it nothing happens. The color is brilliant. I like the compact design for an extra computer. This is the first HP/Word computer I've bought in 11 years. I hope it had better security. Having all in 1 for $400 is a perfect purchase.

Easy to set up
I am not particularly computer savvy and this system was easy for me to set up. The screen has a clear image and so far so good.

Restocking fee after 3 days is outrageous
It’s not a touchscreen which is what I requested in my search. Once it arrived and was set up, I noticed not only was it not touchscreen, it wasn’t wireless. And then to add anything to it, we had to take it out of safety mode which was a risk. I returned it within 3 days and was charged a $80 restocking fee.
