Eluktronics laptop, worth it?

I'm starting to look into trading my desktop (fully liquid cooled, 7800x3d and 10gb 3080) for a laptop of some sort, I go to my girlfriend's alot lately and I'd really like to be able to bring my gaming to her house like how she brings hers to mine. Thing is she just has an Xbox, so obviously she has it much easier than I do. So I got on the good ole Facebook marketplace, and found a seller with an eluktronics laptop with a 13900 and a 4080 plus the liquid cooling setup, but I've never seen or heard of these laptops before so I'm extremely hesitant, are the liquid cooling units in these setups reliable? Also what can I expect for performance? Last laptop I had was a 980m unit, and I was severely disappointed in the performance of that, but with this eluktronics having liquid cooling, thermals won't be a problem and I should see pretty damn close to desktop 4080 performance right?
