I picked up the SmartGoggles Refurbished to help with my bedtime routine, and they've become a regular part of winding down. The vibration, heat and massage settings are soothing, and I do notice I relax faster and fall asleep more easily. The refurbished unit arrived in good shape and works as described. It's not a miracle cure for stress, but as a relaxation tool before bed it does the job well for the price. Heat could be a touch stronger, but overall I'm happy with the purchase.
