Rated 5 out of 5 by from The best money can buy I'm a graphic designer and have had this computer for over a year and I have had no complaints. It's fast and I use it heavily. :)

Rated 5 out of 5 by from Super fast! I bought this a couple of weeks ago.. although disappointed that is is now $500 less than what I paid for it :( It was extremely easy to set up but had major issues with the speed on the wi-fi connection and many pages weren't opening, rang up HP desktop support and were on the phone for a while having to rectify issue and amazing how super fast it is now. HP desk support have followed up 4x in a week for my issue. They were amazing!

Rated 2 out of 5 by from Not good as it seemed I bought this machine in Oct 2018. I came to notice it to have developed a problem; when it went to sleep either after staying idle for quite while or by doing intentional sleep mode as we often do to, it didn't come out of sleep ever. Only option i have now is now to perform forced shut down to make it operational when it fails to wake up from sleep. And of lately it succumbed to another audio issue; its sound has stopped coming through inbuilt speaker. I did troubleshooting for Audio Setting but to get nothing. JB is also rude; they don't want to discuss anything but are asking to bring this huge machine into the store. To make it more worse, the Display is too reflective. You couldn't see anything unless there is dark in your room or home. It's really a horrendous experience with both, HP and JB. Don't go by with aesthetics and spec of this machine but performance, which is truly abysmal. I just regret to the frenzy, elicited by craftsmanship of this machine, ans wish to have never bought it .

Rated 5 out of 5 by from So far so good We bought this model due to the SSD for quicker startup response and it hasn't disappointed. Screen is great and overall design is very pleasing.

Rated 3 out of 5 by from Noise Problem In my opinion, this is a great PC with one major problem. It looks great. It is very fast and easy to setup. The screen is very good. The keyboard is good but the mouse does not seem very robust. However, the problem is that the PC produced a constant whining sound, which sounded like it is coming from a fan. When using the PC in a quiet environment this sound became annoying. I contacted HP support and they were extremely helpful. Eventually they sent me a return authorisation letter and I exchanged the PC. Unfortunately, this second PC also had the same problem. HP support again sent another return authorisation letter and I obtained a refund. From my conversations with HP support I concluded that HP are aware of the problem with this model and have changed the design of the new replacement to correct it. The JB HIFI staff at the branch were friendly and helpful throughout.

Rated 4 out of 5 by from Love It Great all rounder. Amazing display. Great for gaming - runs WOW on ultra high no problem. Also runs Adobe design suite with ease. Dont see the point in the touch screen - still waiting on an excuse to use it. A lot of glare if youre in a bright space.
