I cannot explain how bright and powerful this thing is, honestly I’ve bought so many red lights and returned them but this one ☝️ is unmatched from what I’ve experienced thus far. I’ve only been using it for a bit so I am just starting but I’ve showed everyone who has stepped into my house since I got it. So far my favorite thing to do is use the sleep feature before bed I feel like it calms me and helps me sleep better. I’m using it for all the other things as well but I would not hesitate if you have pondered dropping the money on one, I’d definitely recommend this one. I got the biggest Biomax Pro Ultra and have it on my door I angle it and lie on my floor for now. I REALLY wish I could have afforded the adjustable floor stand so I could lie on my bed or couch it would make my experience so much better!
