I've used mine for a couple weeks now and it is amazing. I see other reviews complain about the speakers. . . nonsense. Use bluetooth and the quality is amazing. The lights are cool yet I find it more relaxing to be in the dark with the music for sure. Don't bring your phone in, but have it playing music for you. DO buy the $75 cushion that comes with this. Assembly is a bitch, nearly impossible with just one person (as I did). Read the assembly manual carefully as I did not and wasted a lot of time. Keep the vent closed above to increase the heat for sure. Install the tray, but use it as a cup holder for sure. It supports my 32 ounce tumbler which I bring in. Over the 30 minutes I stay in I steadily drink the entire tumbler, but I also load up on water before I enter for sure. APPLY ALOE VERA OIL or some other moisturizer to skin closest to the panels. Go SHIRTLESS as you will sweat much more. If you wear clothes it ruins the whole damn thing with infrared rays. TRUST ME ON THIS. But the dry heat needs to be addressed with oil because for the first 15-20 minutes you won't be sweating, but the last 10 you'll be POURING BUCKETS. I wear crocs or rubber sandals that are easy to wash because the floor panel will be too hot for your feet. You can wear your shirt, but you get the best effect without. At a minimum put oil on the outside of your arms and shoulders and back of calves and anywhere that is subject to the direct infrared rays. OIL IS KEY unless you're coming from a pool or hot tub or a sweaty workout. DON'T BE HERO especially if you just got done working out. DON'T LET the temperature gauge fool you. This thing puts way more heat into your body that is shown by the thermometer. Progressive overload yourself, but don't endanger yourself by staying in too long. BY HYDRATED. NO ALCOHOL. EAT HEALTHY. Most importantly take a shower IMMEDIATELY afterwards to wash the toxic sweat off and slow graduate it from cool to cold as a final COLD SHOCK to seal the deal and get MAXIMUM health benefits. Trust me, I am a heart disease survivor. Eat healthy and you'll be able to sustain more heat for longer with more ease. Any questions just ask.
