After owning the last Helios 300 (GTX 1060) and selling it last year I was ready to be done with the Predator laptops.  The old red laptop was just too big and bulky, and between the thermal issues and instability with the OS I was just done with it altogether.  Then they released this Helios and I'm truly blown away.LOOKS- For starters it is a thinner, sleeker, lighter, and much more visually appealing laptop compared to the big red "gamer" aesthetic they were going for with the old model.  While performance matters more than looks to me and while it was a tremendous value for the price, it certainly drew a lot of attention for all the wrong reasons.  This one is a thinner, more modern looking computer with cleaner lines and a smaller profile while still keeping the same screen size.  The blue theme to this is more appealing VS the red and I use it for gaming as well as at work.  My colleagues presume it is a professional laptop but little do they know it is also a gaming powerhouse.PERFORMANCE- The 1660ti is only 7% weaker than my GTX 1070 that is in my PC tower.  It will play pretty much anything at 1080p ultra settings with fantastic frame rates.  Combined with the 144hz screen it is only trumped by my 4K monitor on my actual battlestation at home.  You can look up benchmarks if you're interested, but bottom line here is you'll have no problem with 1080p gaming.  If you want to do 4k you can output to an external monitor.  But that isn't the point of using a laptop.KEYBOARD- It's also an improvement over the previous Helios 300.  It's no mechanical keyboard but it is definitely responsive and comfortable to type on.  The inclusion of a numpad is also a plusSCREEN- Crystal clear with a high refresh rate.  By far the best I've seen on any laptop.  Mine didn't have any screen bleed but I can't speak for everyone.  Good size and the colors are nice and clear.BATTERY- It's simply OK.  You're gonna have better GPU performance with this plugged in but I can see general tasks being done on this for maybe a few hours before it needs to be plugged in.STORAGE- The 256GB drive is an M.2 drive and is crazy fast, but it doesn't hold a lot.  You can add another M.2 drive and there is a bay to add another Hard drive or SSD.  You'll have to actually wire the drive into your motherboard (the old Helios had the port pre-installed) and this is a service that could actually void your warranty.  It isn't the hardest thing to do, but I would definitely recommend taking it to an Acer care center if you can't figure it out.FINAL THOUGHTS- The new Predator Helios 300 is worth every penny.  With improved stability, thermals, looks and performance it is a no brainer.  This thing is gonna be the replacement for my PC tower if and or when it finally kicks the bucket.  If you held off on buying the last Predator due to all the issues you heard about I would say you made the right call.  This is the solution to those problems you were waiting for and then some.  If you're on the fence I can wholeheartedly say (with my name on the line) that this laptop is absolutely worth it.  Yeah it's expensive and I wasn't too thrilled about shelling out for another Predator after all the problems with the first one, but I am glad I got this and I know you'll be too.
