### ⭐⭐⭐⭐⭐ 







  
  
    Bought 3, and they work.
  

*by X***X on Reviewed in the United States on 4 October 2024*

Was rebuilding my home network, bought 3 of these and have been pleased.  My media boxes run Ubuntu, my primary desktop dual boots SuSE Linux and Windows 11.  These cheap little cards work with every distribution out of the box.  Tried Fedora 40, no problems.Speed is good, stable connection, no complaints.

### ⭐⭐⭐⭐⭐ 







  
  
    Does what you want it to do.
  

*by N***O on Reviewed in Canada on 18 March 2023*

This runs perfect in my pc. My internet connection is stable and runs at full speed. I even get the 2,5gbs intranet connexion from my router. My internet plan is only 100mbs so that doesn't benefit of the full 2.5gbs obviously but maybe in few years I'll get an optic fiber connection that will take advantage of that pciE card. This was easy to install and has no Cons or whatsoever.

### ⭐⭐⭐⭐⭐ 







  
    Super carte réseau
  
  

*by L***T on Reviewed in France on 27 August 2024*

Carte d'excellente qualité et très facile à transformer en Low Profil pour des PC de petite taille. Les Débit sont vraiment top, j'adore ^^
