## Questions & Answers

**Q: Most of the newest 5 star ratings come from people with exactly one review in their history.  Is anyone getting real aftermarket support for defective units, or it all still a game?  What a shame for a product that actually works.**
A: I have had my Tendlite for almost 3 years now with no problems with the device.  I feel it does help, as long as the injury can be helped with increased circulation around the area.  I had a question about air travel with the device and the Tendlite support group was very attentive and helpful.  It is cheaper to buy it today than it was 3 years ago.

**Q: How is this device different from the light relief device?**
A: Dear Gary,The main difference is the Power. TENDLITE has more than 4x the power of the other brand. TENDLITE is a Professional Grade Medical Device. Now Tendlite comes with a set of Rechargeable Battery + Charger.All the best,Team TENDLITE

**Q: Is it effective on finger joints or the knuckles?**
A: Yes! The Tendlite is indicated for Temporary relief of joint pain, and relief of arthritis pain.  In fact, due to the size and portability of the unit, you can target a finger joint directly, getting all the energy right where it's needed for pain relief.

**Q: Is this the 2014 model using 3 batteries?  How many 1 minute sessions can I do at a time and how many times a day?**
A: Dear Viewer,
No, this is actually the new 2018/2019 model, it uses 1 large rechargeable battery. It comes with 2 batteries (1 spare battery) and the charger.
Usually, you will do a 1-minute session per spot/area. If the pain is intense, you might want to use it for 2 minutes per area.
It is a safe technology, you will not hurt yourself by using for longer than that.
Please let us know if you have other questions.
All the best,
Team Tendlite

### ⭐⭐⭐⭐⭐ I am a big fan! EDIT:  FOUR YEARS LATER BOUGHT ANOTHER!  Fantastic!
*by K***M on November 8, 2018*

Below you will find my original review from 2018. I have used that device steadily for four years, with an additional purchase of the specific batteries required two years down the road. Now I have decided that in spite of the fact that my old Tendlite is working away nicely, I am going to be proactive and now have another one in case the older one gives out due to the constant use it receives!These are WONDERFUL! They far exceed the results that my chums' other brands of red light pain reducers are able to achieve. THIS IS AN AMAZING DEVICE! My only caveat is that you must use their proprietary batteries if you need replacement batteries over the years...I ordered mine without any trouble from the company.Here's my original review:Bought this because of how much relief red light therapy gave my late ancient Jack Russell terrier who suffered terribly with arthritis until our vet started her on this kind of therapy. We had two and a half happy years that we would not have been able to enjoy together, all due to this kind of therapy. She lived to the ripe old age of 17 and a half, even with assorted health issues. The arthritis was managed beautifully by regular red light treatments, and was not a negative factor in those last years.This is not exactly the same kind of device, but it is the same kind of therapy. I now suffer from arthritis in my knees and from a Morton's Neuroma in one foot. I stumbled upon the Tendlite device during a browsing session on Amazon (so much easier on the knees to "browse" an on-line store rather than walk all around the town), and gave this a try.Based upon my dog's results, I had pretty high expectations for this, and I have been absolutely delighted with the results I have had so far. I have carefully read and followed the directions, and selected the three treatment cycles (one minute each), three-per-day treatment plan for my knees, which is the most intense. After about a month, I have had excellent results!Don't get me wrong...this is NOT going to cure my arthritis. What it does is significantly reduce the inflammation in and around the joint, which reduces the pain and stiffness. This allows me to exercise more, to use my knees better, to walk better...in short, it is a game-changer for me.In fact, I have had so much help from this device that I now use it on the ball of my foot that has the neuroma, and to a lesser degree on the top of that foot, directly over where the neuroma is located. I treat these two areas only one time each per day. [The device times out after one minute, so a single treatment is always one minute in duration.] The improvement in this poor foot has been nothing short of astonishing! I can't know if others will have such a remarkable improvement, but I wanted to share my results with other sufferers.This is easy to operate, although a bit hard to hold as it is the size of a small flashlight... and with somewhat stiff fingers I worry about dropping it, and comes with an operations booklet that is murder to read, as some pages with needed information are the teal color that seems to be the device's hallmark. Why would this wonderful company print info on such dark pages? Yikes! I had to enlist a kind teenage neighbor who had to use a special crafting light in order to read the information aloud to me. Aside from that glitch, I am DELIGHTED with this remarkable little device. BRAVO!

### ⭐⭐⭐⭐⭐ Very happy with the results
*by S***R on March 22, 2020*

I bought this because this kind of light therapy was recommended on a dental website that was talking about dental implants where they drill the anchor screw into bone. Nerve damage can happen with dental implants. I had a traumatic extraction that left me with significant nerve damage. Nerves take a long long time to heal and psychologically it can be a rough journey. Since this kind of red-light therapy was recommended, I figured it was worth a try. I have been using it now three times a day for five days now. As far as pain goes, I don't use it for that reason, but I did notice that it reduced some of the bone pain that comes and goes. It doesn't work as well as medication and it doesn't last as long, but it definitely did help. I should also say that I used it for just two 1-minute cycles and the pain relief was just some relief for about an hour. Even the instructions state that it may take up to 3 weeks of regular treatment to notice a difference, and judgment should be withheld until after 3 weeks of use. I haven't had it that long, so I can't comment on the truthfulness of that statement. I also have significant arthritis in a finger that was made worse after trigger finger release surgery. I also plan on using it for this finger, but I have not done so yet. My dental issue far outweighs my finger right now. I should also mention that this was the only unit that had the light power that was recommended on the website for dental issues. I will have to do an update after I have been using it for at least the recommended 3 weeks. I can also say that when I use this unit, my nerves will slightly tingle, so I want to believe that there is benefit to using this. I'm dealing with a significant amount of numbness and feeling that tingling builds my confidence that the feeling in my lip and chin will return. So far, I am happy with this product. I would not purchase this for wrinkles and beauty benefits because the instructions state that it will not help for that. I suppose you could try it since I have seen so many YouTube videos about how it works for youthful appearing skin. I have my doubts, but I'm not using it for that anyway. I hope that when my nerve injury is healed, I will still be able to get my money's worth in using it for arthritis.UPDATE: It is now April 5th and I have been using Tendlite for 18 days, 2-3 times a day for 3 minutes each session. The first week I did not notice any change, but again, even the instructions state to wait until after using for 3 weeks before making any judgment. Today, I can say that the feeling is about 90% returned in my chin and 80% returned in my lower lip. I still have some numbness in my lower lip. The healthy tingling I used to get is still there in my lip but I'm getting more and more paresthesia (nerve pain) as the nerve heals, which my dentist says is normal and will resolve over time. The greatest pain is during and just after eating, but once I finish, the pain gradually subsides. I can press my lips together and get full sensation. In summary, for the first 3 weeks 2 days before using Tendlite, there was no change at all in the 100% numbness that I had from a traumatic dental extraction. After using Tendlite for 18 days, I am well on my well to healing with near full sensation back. The big issue now seems to be the relationship between the nerve and muscle movement. I will continue to use Tendlite because I firmly believe that it has helped with nerve damage. As I stated before, I got the recommendation from a very medical dental website that recommended near infrared light therapy with at least 660 nm light that Tendlite has. I was not able to do a comparison on another nerve because I only had damage on one side. But I am convinced that once I started using the red light, improvement came much faster than it probably would have. Considering that it usually takes several months to recover from nerve damage, I think I am ahead of the process with the help of Tendlite. I'm not a doctor or a dentist, I just know what I feel. I have used the unit after eating when the nerve was its most irritated and it did feel pretty good. That too helps me feel I'm better with it than without it.
