VRSmash

You've been hearing about virtual reality porn for months, you finally saved up to buy a good VR set, and now you don't have money for a premium membership. Don't worry, VRsmash.com has got you covered. This free site has over a thousand scenes in their collection. You can find gay, straight, lesbian and shemale content. There's sensual sex, rough fucking, blowjobs, various fantasies, and fetishes. 

If you sign up for free, you get to download HD and 4K videos instantly in a variety of formats, favorite them, upload your own and post comments.  Most videos on VR smash are not full length, but rather teasers that last around 5 minutes. Quality is good, and playback seems smooth. There is support for all the major headsets like Oculus, HTC, PSVR, etc. 

The user interface doesn't stand out much. You have your typical thumbs with previews and some video info. There a list of important categories, and the ability to sort content by 180-degree and a 360-degree view and a 360 VR player that lets you browse and play scenes. There aren't a lot of ads, but you might find yourself being redirected from time to time when clicking on categories or something similar. Overall, VRsmash seems to nudge you towards premium VR sites. One of the biggest drawbacks is the lack of a volume bar when streaming. 

VRSmash is an excellent place to start your adventures in virtual reality porn but has a few drawbacks that might push you towards other free sites or even premium ones.
