It's nice to get to use it. The bad side is, it's blurry; I don't know how much is my eyesight, and how much is the device. But words are hard to read. Some controls are unintuitive also; pressed a button, and a Windows menu popped up in the game, hard to get rid of at first. But, we'll see how it goes. I'm glad there isn't screendoor.
Are you looking around with your eyes or your head? VR HMDs have one large drawback: the sweet spot. Essentially, the center of the lens is the most clear, and as you move outward, it becomes fuzzy. Some HMDs have worse (smaller) sweet spots than others, which can become a bit of a drawback.
Also, as mentioned, wearing glasses/contacts does help too. I use specific lenses that are tuned to my prescription in my Vive.
