This is an effective and durable design. It has the infrared frequency needed for accelerating healing and at 200mw/cm2 it is at the top of the irradiance range needed to penetrate deep enough to accelerate cellular regeneration and therefor healing of deeper body tissue areas like the back and neck.
It is very effective and easy to use on both the upper and lower back. The heartbeat mode works muchwr better than the fast flashing LEDs of cheaper devices. I use the constant on mode at first ad the heat from that help relieve pain when it is a fresh or acute injury. I alternate it with ice twice a day until swelling is mostly gone then stop the and continue the infrared pad on heartbeat mode 10 minutes twice a day which produces noticeable heading progression that seems to be not quite twice the rate of healing without the infrared treatment.
It is not perfect for the neck which is my other chronic pain area as it is too wide and overlaps the chin and shoulders. It is however better than the other pads that are powerful enough to work in that it is very flexible and bending and creasing it has not broken the circuits as has happened with other more rigid pads. The ideal for me would be this in a shape that fits the neck and maybe another one for the shoulders and upper back. There are several of these on the market but they are not powerful enough to work like this one is. So for now this is the best solution out there by far even though it is not perfectly suited to my needs.
The controller being separate and visible while you use the pad is nice and handy too.
I did try this with a 10000 mW lithium battery and it seemed to work the same with the same output as when plugged in. It did appear to drain the battery rather quickly but I did not test it to see how long it would run it.
I would give it a 4.5 and not a 5 only because it is not designed to be easy to use on the neck. Otherwise it’s a 5.
I have been using for 4 months twice a day where ever needed and am amazed with the results. My joints and muscle pain is amazingly better. I also had an issue with the first pad and just an email and pictures of problem and I received a replacement
I bought this to help my bones as I have osteoporosis, and I won’t know if there is a benefit for a few years I imagine. But after 4 weeks I noticed I was sleeping much better, soundly, deeply and my circadian rhythm returned. I noticed that my hormones feel more balanced. I notice that my body is not stiff and sore after exercising, and I feel like I have way more energy. I feel like I've been given a “tune-up” at the cellular level. Now it is my go-to for any niggles in my body. I had a few issues with the pad and cable, and the company quickly sent me a replacement and I hear that the new models are stronger and more durable.
I use my device daily and have noticed I don’t have bleeding gums, still hoping it’ll help with receding gums as well. I’ve been using for a couple months now. I had an issue with the controller remote and customer service was GREAT! That says a lot about a company that will reply and fix the issue promptly. I truly appreciate it :)
