Overall, I'm satisfied with customer support, delivery and quality of the chair. I've had this chair for 3 months now and I will say, the 4D dual mechanical technology is the only way to go when getting a massage chair. This chair is loaded with customizable programs and features and I like the separate adjustments for the upper back and lower back/glutes. Another nice feature is the pain relief detection technology to scan your body for sore areas and it'll adjust accordingly. Only a few minor things. I feel the seat could be at least 1 inch wider because it feels a bit snug for a 6ft, 2XL size guy. Don't like using the voice commands because sometimes it turns on by itself, so I don't use it. Lastly, no ability to do software updates.
Overall, I recommend this chair and hope it'll last me for years to come.
