I have had 3 VR head sets ….. Rift CV1,, Samsung Odyssey standard and the Pimax5k+ . I think the Pimax is the most immersive and the clarity is the best. The Rift S is cheaper in price and I have tried one out but Pimax is better in my opinion. I use the Pimax at max field of view and it makes a difference in emersion . Screen door is not even an issue. Some people says that it has some distortion at the edges of the ultra wide settings but who the heck looks at the edges in real life. You turn your head to look at what you want to look at unless you have neck problems. Pay the extra money and you will have a headset that will not become obsolete foe a good while. I Didn't use the head strap that came with the unit but purchased a Deluxe Vive auto strap for $65 on Ebay and 3d printed the lugs that snap the Vive onto the head set
