I purchased the BioMax 900 along with the Horizontal Stand. I’m pleased with the purchase so far and use it every other day. I think the Horizontal Stand is a big reason for me to stick with a regular use plan. I probably would grow tired of standing in front of the unit. The stand allows me to lie down on my bed while using the BioMax and it is very relaxing. I can position the stand to cover my upper and lower body while laying on my back and then laying on my stomach. The height adjustment enables me to position the lights approximately 8”-10” from my body. I set the timer for 10 minutes for each of the four areas (upper & lower body both front & back) and it takes 40 minutes total. I'm still new at using the BioMax and withheld giving it 5 stars until I have more time to provide a more thorough evaluation on how it makes me feel.
