Easy to use and well built. I've noticed an improvement in the appearance and smoothness of my skin after a month of daily treatments. Treatments leave you very relaxed. I find the therapy very effective for pain relief of the joints and muscles after hard workouts or injuries. I have recommended PlatinumLED lights to nearly all of my friends because of the numerous health benefits. Customer service is solid. I was originally shipped the wrong product for my order but had a call tag within 24 hours and the package was reshipped next day air and affived on a SUNDAY!
