These are impressions from using my Portal for 2 hours of uninterrupted Final Fantasy 16 play
Pros
-Plays super smooth. No lag whatsoever
-Easy simple setup. Took about 30 mins between powering it on, setting up Wifi, and connecting it to my PS5
-Screen is impressive. Game plays at full 1080p and cutscenes looked really nice on the 8inch LCD
-Haptic feedback and rumble is the exact same as on dualsense. Your literally missing nothing
-Sleek design, not too heavy
-responsive controls. Again feels just like using a dualsense
Cons
-Lack of bluetooth for most without standard wired headphones means listening from crappy speakers
-ergonomically, its kind of weird to hold. I feel like the spacing is just a tad too wide. I like to play laying on my back with my hands up while up looking at the screen propped on a pillow. This position cramped my wrists and made it hard at times to hold. It seems like Sony really wants you to either lay on your stomach and play or be sitting up and looking down, which I did for stretches but thats not my preferred method of playing.
Overall this device is EXACTLY what Sony has marketed it to be and not one OUNCE more. Its as barebones as it gets. Its for mirroring your PS5 over Wifi. Thats it. No surprises. And for that singular purpose, this is the best device i’ve ever used. I used my Vita to remote play Kingdom Hearts 2.8, Final Fantasy 7 Remake, and Final Fantasy 7 Crisis Core Reunion. All three times were very annoying experiences with noticeable lag and annoying dropoffs. There was not one single LICK of lag while playing FF16 on the Portal.
Also its good to keep in mind regarding Wifi, I live in an apartment thats not super big and due to my work (Film director) I have the best Wifi that Xfinity offers AND my PS5 is connected via ethernet to my router, so in my case there shouldn’t be any lag at all. Your experiences may vary
