User opinions and reviews

Hi, excuse me, this K40s (prob F4 vanilla) with vapor chamber liquid-cooled heat dissipation system vs the K40 (F3) with liquid-cooled copper tube... Their perfomance is almost the same or what? I mean, is worth to wait for the F4 or I should go now ...

Is this really gonna be the normal f4? Or is it gonna be the k50?

Thanks for the tip! Unfortunately, there was a sale recently (for one day) and I got the Note 11 Pro+ 5G for about $25 cheaper [same price as the early bird deal - guess it was the late bird deal]. Should arrive in a few days. Fingers crossed I won&#...
