@nanmora I haven't used it a lot as yet, but it is very great feeling the rollers and outer things you feel! It has a red light on the one I got which is the higher priced and has more bells and whistles. The only thing I'm not happy about is it is hard surface and you must get it in the correct placement on your back or you get a sore lower back!!!! I just ordered their red light belt to use for 15 minutes and their electric small stick on units for my spine. C4 & C5 Lombards are coming together as the cushion that separates them losses fluid as we get older and that is why they come together!!! And guess what the nerves go between the Lombards and that is what causes the lower extremities become numb!!!! My physical Therapist just gave me what I think is the best information of all the Neuropathy guys I have seen. The thing we need to do is work on our insides, not creams and all that stuff the SNAKE OIL SALESMANS want to sell you. Here is the product has B1 in it BENFOTAVNINE-Fat Soluble. The other 0ne is THIAMINE- Water Soluble if you take this one you will drink 6 glasses of water a day and you will urinate along with other fluids, so that doesn't stay in your body long enough to help you!!!!!! The Fat Soluble will stay in your body all day and that is the best choice!!!! He recommended the best guy to watch for all Neuropathy is on YOUTUBE- EO NUTNTION, His writing is hard to make out the letters, so hope I'm close to the correct spelling!!!!
