I have had this laptop for almost 3 weeks and have been putting it through its paces with general use, games, watching streaming videos, etc. before writing this review.=======Pros:=======* Cooling is MUCH improved over the 2018 PH315-51 model and comes factory under-volt by -0.125v which certainly helps.* The screen bezel is a lot thinner than the older models. The screen just feels bigger now even though logically, on paper, a 15.6" screen is a 15.6" screen.* Has a DisplayPort* All USB ports are USB 3.0 (Instead of 2x 2.0 and 1x 3.0 as on the older model)* Gaming performance is great* Overall performance is great* Boot time is insanely fast on the NVME drive. Around 10 seconds or so, if that.* Screen is beautiful, colors are vibrant, the view angle is fantastic, and the 144 HZ refresh rate is great; although please see my gripe about discoloration of the top of the screen in the Cons section.* The touch pad is nice and spacious* It is pretty light as far as gaming laptops go. I've seen some people complain that this laptop is heavy; but coming from an older gaming laptop that weighed almost 15 pounds... The weight of this laptop is a major relief!* The keys are back-lit which is great for low-light/night time computing/gaming* The chassis is nice. The top (back of the screen) and the keyboard area is metal, while the bottom and the bezel surrounding the screen is durable plastic. I absolutely love how nice and cool the metal is against my wrists when I'm typing.=======Cons:=======* My biggest gripe about this laptop is that there is visible light/color distortion at the top of the screen that is very noticeable against dark backgrounds. This is very distracting if you're watching a movie and there's dark scenes, or if you like to play horror games where typically the environment is dark. I've noticed a lot of people calling this light bleed and I've seen multiple screenshots of the effect; but this isn't light bleed (Well, it might be in the technical sense of the word). You know how if you press your finger lightly against an LCD screen (I'm NOT recommending that you do this by the way), it discolors slightly around the area where you touched? That is what's happening here. Apparently the bezel at the top of the screen is pressing WAY too freaking tight against the top of the screen (From factory!) and causing the discoloration at the top of the screen. I can't imagine that this is good for the health of the screen. This NEEDS to be fixed.* NVME drive is small at 256 GB. There is 237 GB usable, but realistically, there is less than that due to operating system install, so there is more around 130 - 150 GB of free space for applications, games, etc. You can load a handful of modest sized games or one huge game (Doom 2016 is around 80 - 100 gigs after patches and Final Fantasy XV is around 90 gigs after patches. Sheesh, game sizes are getting absolutely ridiculous!). That little drive will be hurting for free space in no time at all after a few games are installed. You will definitely want to add a spare drive to put games on. Acer claims that the laptop is expandable with a second NVME drive and a 2.5 inch bay (Which does include the connector you need for it in the package), but the entire back has to come off if you want to put a drive in internally, and you might void the warranty in the process if you do it yourself; so it's not a false claim, but it's a 'gotcha' claim. An external USB drive is the way to go if you want to remain on the safe side and don't want to pay a tech to put a drive in for you.* Battery life is OK; not great, but not bad either. When not gaming it can get about 3 - 4 hours of light use. It is absolutely horrendous when gaming at approximately 50 minutes, give or take a few depending on the game. Although I will say that this is to be expected from a gaming laptop. It's a lot of power packed into a tiny device. You will definitely want to be plugged in if you want to game on it for any extended length of time.* The webcam is horrible. It is -technically- HD in resolution, but only in resolution. The picture quality resembles early 2000s webcams. The video quality is something between a VHS recording and low quality grainy DVD. You'll either want to get an external webcam or pass this laptop up for a different one because this webcam sorely disappoints. It will work in a pinch though. I will note that it helps a bit to have a very well lit room if you want to use the webcam; even so, it's still pretty bad in my opinion. In the end it doesn't matter to me personally since I don't use webcam that often anyway.* The sound quality of the microphone is not fantastic. It sounds like someone is talking through a tin can. Like the webcam though, It will work in a pinch. I don't use microphones that much anyway, so it isn't a big deal for me.* The speakers sound piercing and tinny. No bass whatsoever. This is to be expected though, most laptops don't have the greatest speakers anyway. Use headphones or an external speaker system whether wired or blue tooth.* Acer seems bent on making installing your own OS on this laptop as hard as possible; even if you want to install a different edition of Windows 10 (For example: It comes with Windows 10 Home but you want to upgrade to Windows 10 Pro). It is doable but be prepared to do a little digging and research to figure out how to do it. I would expect this kind of crap on a low end cheap laptop, but NOT on an expensive gaming laptop!* UEFI/BIOS settings are bare minimal. You can tweak a few boot settings and that is about it. It is definitely NOT a power user's utility. Again, I expect this on a low end laptop, not a gaming laptop.=============================================Mixed Feelings that are neither Pro nor Con for me:=============================================* Although cooling is much improved over last year's model, for some games, you will want to turn the fan to max. Keep an eye on PredatorSense temps. I personally prefer to max the fans if I notice the temps getting higher than about 75, but that's just me.* There is a very limited amount of USB ports if you're not counting the USB-C connector, there are 3x USB 3.0 ports. Invest in a powered USB hub if you need to plug in more than just a keyboard and mouse (Because who wants to game on a laptop keyboard and touch pad unless they had no choice?)* USB-C connector is data only; does not output video* There is no optical disc drive. Not a big deal since USB drives are cheap nowadays, but it would have been nice to have.* You have to be slightly heavy handed on the touch pad but this may come down to user preference. Personally I'm fine with it and I'll be hooking an external mouse to it whenever possible anyway.* Keyboard back lights are not RGB. They are solid blue/light blue in color, you can toggle them on or off, and set a few different levels of brightness on them. Not a big deal for me though; I'm just happy being able to see the keyboard in the dark.* There is pretty minimal bloatware pre-installed, but it is no where near as bad as other computer brands. I would consider it a reasonable amount to be honest.* The dual GPU set up can be confusing at first. A tip for anyone first time to dual GPU: If you're having trouble figuring out why some applications are performing badly and they don't seem to be using the nVidia GPU; close the program, then right click it, and chose Run application with GPU > High performance nVidia. You can also set up an application profile in the nVidia control panel for your program to use which ever GPU you want if you want the program to always run with that.Despite some faults with this laptop, overall, I like this laptop a lot.
