Bests & Worsts Reviews from Amazon

THIS IS SUPER IN 94 I HAD BACK SURGERY ON L5 S1 THAT'S WHERE YOUR SPINE IS CONNECTED TO YOUR HIPS. THIS IS THE FIRST GEL PACK THAT'S IS MADED FOR YOUR LOW BACK., I CAN STRAP IT ON KEEP GOING ,THE GREATEST PART IS YOU GET TWO GEL PACKS , BUT REMEMBER NO LONGER THAN 20 MINUTES AT A TIME COLD OR HEAT. I PREFER THE COLD THE PAIN RELIEF LAST LONGER. I'M HOT NATURE , I'VE KNOW ABOUT THE USES OF ICE SINCE 94. THIS IS SO FANTASTIC IT'S A MUST HAVE FOR LOWER BACK STRAP ON & GO , NO LAYING IN BED ON TOP OF ICE BAG & DAMP TOWEL WITH YOUR LEGS PROPED UP. I HAVE TWO 26 YR OLD SCREWS HOLDING ME TOGETHER. SCARY ISN'T IT. THESE GEL PACKS ARE SUPER.
