## Customer Reviews

### ⭐⭐⭐⭐⭐ ROG Ally with a 3080... No complaints here
*by G***. on July 21, 2023*

The media could not be loaded. So, every negative comment I've ever seen about the XG mobile with the ROG Ally was pretty much false for me with one exception. The fan is loud under full load but my sound is usually set louder. I don't understand the negatives here. I even tried to break it and see what the problem is. It docks and undocks just fine. It's ridiculously powerful. I have the desktop version and I honestly am 2nd guessing even owning a desktop right now. Granted, I'm playing at 1080p on a mobile monitor but the FPS is perfect for pretty much all modern games on ultra. I'm using an SSD on USB as extra storage for games and it works fast as expected. I thought I'd be pissed about no USB C but the version of USB A is still plenty fast for SSD gaming. I am returning this one from Amazon because I bought one direct from Asus shortly after for much cheaper. I don't understand why they're so much higher on Amazon. Be patient and pay MSRP through Asus. The 6850 should be $799 and the 3080 should be $1099. Just create an Asus account and click notify on the product. They'll email you when in stock. Lastly, I saw complaints about the pcie X4 vs x8 speeds blah blah blah. Supposedly there's lag with keyboard and mouse. Total bs. I don't know what speeds they are but my FPS are typically around 90-100 on CoD and I have no lag on my keyboard and mouse. It plays like a desktop PC. I'm using all ROG gear for my setup down to the mousepad. I average around 60 FPS on CP2077 with the RT Ultra preset @ 1080p. That's hella good for a modular mobile gaming setup.

### ⭐⭐⭐⭐ Super expensive but better than universal egpu
*by S***G on October 20, 2024*

I combined this with the i5 z13 asus gaming tablet and it works very well. I compare it to an amd gpu I combined with razer core x egpu, and I think the asus proprietary system is better performance and more stable. I was debating keeping it because it's so expensive but decided to keep it since I got my gaming tablet pc for cheaper on woot.com.Pros:- very compact laptop ver 3080. Easy to transport as needed in luggage or a backpack.- doubles as a pc dock has everything i want except usb c.- proprietary connection is better performance and stability than other universal egpu in my experience.- easy to upgrade drivers with Nvidia software.Cons:- so freaking expensive def wait for amazon sales.- fan gets super loud in full turbo mode. Headphones is almost a must.- temper your expectations. It can't run everything at 4k 60fps ultra settings. On a samsung HDTV I typically have to set 1440p 60fps with Nvidia frame generation with older aaa titles like last of us, red dead reception 2, cod modern warfare etc. Works well for 2k gaming. I can get 75+ fps ultra setting at 1080p but prefer higher 2k res vs more frames.- I think they're discontinuing the proprietary connection? The newer refreshed asus z1 extreme handheld gaming pc ditched it for usb 4 c connection. If true then this and the 4090 version should be cheaper! Smh!

### ⭐ First order, DOA; second order, also DOA
*by C***E on February 23, 2023*

When i first got the X13 Flow, the NVidia-based XG Mobile failed after a couple weeks. I had to send the laptop in with the XG Mobile because apparently they don't have any spare laptops at Asus repairs. The replacement XG Mobile failed after a few weeks but i didn't bother RMAing the replacement XG Mobile since i needed the laptop.I was delighted to see that the new AMD-based XG Mobile was available on amazon. First one was DOA -- the X13 would receive power from the XG Mobile, but armoury crate would never prompt to switch to the XG Mobile like it was supposed to, and no fan noise whatsoever from the device itself. Asus wanted me to RMA the unit, but i just returned to amazon (because I am not an idiot). The replacement i ordered which i just tried to plug in, is also DOA.I think they must wear those really big shoes in the ASUS QA department and use a lot of pancake makeup because that place is a total clown show.
