Residential subscriber here, reviewing after only a couple of weeks -- If you enjoy hi-def (and in many cases 4K) videos of some of the most picturesque natural landscapes from around the world some with natural sounds or comforting background music (and NO annoying narration), the value here cannot be surpassed. The music (I would describe as new age) is not invasive at all to me, but others prefer the natural sounds . For me its a very effective therapy and I stream this almost constantly when I am home and the stress relief is amazing because I can get lost in the moving displays of beautiful terrain, beaches, mountains, tropical islands, waterfalls, and night sky to name a few etc., or simply have it on in the background as I go about the house. These are not all fixed-camera, many are filmed from above from a drone with a highly stabilized camera mount -- how they keep the motion so stable is a very important feature -- no distracting jerky motion.
There are over 250 videos according to David's website, I have barely scratched the surface exploring the variety. I think some have two versions (natural and background music). I don't do yoga or much exercise indoors but there is also a series of videos for meditation and deep sleep.
I couldn't recommend this any higher for those that need or want stress relief or just to enjoy the relaxation the videos provide. At the time of my subscription, there were discounts available.
