Bests & Worsts Reviews from Amazon

As a first time buyer for "Rechargeable Hand Warmers", I did my homework/ spent time reading a majority of reviews on products where an acceptable amount of reviews are available. I mostly avoid products with limited to none Reviews. On this occasion it really payed off!!!$$$!!! To keep it short in comparison this product stood out for good 👍 reviews 👌 given by a good number of random verified buyers. No one had anything bad to say. In the sea of others where the bad reviews ranged from mostly: "does not deliver on the advertised amount of hours it will operate", to complaints about thermostat problems "Inconsistent temperature changes", and problems with battery charger indicators". This unit 😍 passed all the specs of 12 hours on temperature setting #1. I actually clocked my first set as follows: (1-Set/ 2-Units) 1-Set in lowest Temperature setting/ 1 red light on display = OVER 12 HOURS ACTIVE AND CONSISTENT HEAT. Unit (A) Was Fully Drained and Auto-Off at about 12.5 Hours. Unit (B) Was Fully Drained and Auto-Off at about 13.5 Hours. So basically "Above and beyond" !!!$!!!$!!$ With the Charging on both meeting the advertised time of 12 Hours, with one actually going 12.5 hours and the other hand-piece of the same package set gave out a full 13.5 hours at setting #1 which I used/tolerated comfortably in my gloves, and the pockets of a double breasted pockets shirt, with a cotton Tshirt underneath. It was good for moving in and outdoors in Chicagoland winds in the low 30s Fahrenheit. I also had my doubts about the duration when reading some of the technical specifications in reference to the battery size, after reading other product reviews complaints about short operation life, and with a 5000mA battery. Thinking this one only has 4000mA,???? And yet in practice I can now see that it has everything to do with the "Design" of this product, how it outperformed the others with larger battery specs. Since I was so impressed with my overall first purchase, I bought a second pair. Immediately put on trial/ to the test!!! Thinking 🤔 can it be??? And in short, "Yup" 🤩👍🤑🤑🤑✌️😎 Credit where credit is due. Lasted the exact same. For some reason one piece lasted longer than the other, but both lasted MORE THAN THE ADVERTISED 12 HOURS in setting 1. And About 6.5 to 7.5 hours in (Setting #2) which gets quite 🔥 Hot, and gave me excellent support for sustained movement in Freezing Chicago windchill at 8 degrees Fahrenheit. I am writing this as the Winter in these parts gets started. As of now I have not seen the need to use setting #3 WAY HOT🥵 At temperature setting #2 It has to be really cold to comfortably tolerate these thru my pants pockets onto my legs without any added leggings, like jogging pants or long John's/ thermal leggings. At temperature setting #2 these are too hot to hold directly in the hand, or put in your gloves for a sustained period 😳. As handwarmers directly on the skin of your palm, temperature (#1) the lowest setting is perfect/ Comfortably tolerated for sustained periods of time, in your gloves for example for hours at a time, 🥰 and gives me over 12 hours working time. One more point on the battery and Design. BOTH MY UNITS HAVE PROVEN TO PUT OUT MORE THAN 12 HOURS on setting #1 and over 6 Hours on Setting #2 OF Flawless "CONSISTENT HEAT TEMPERATURE" #1)Hot/warming, #2) Hot/Hot, and #3) Hot Way/Hot, Unwavering, evenly, without a glitch. The led display is easy and very easy to use and see in the dark. Temperature settings 1,2,3 in solid red LED. Press and hold the Button until the red light turns on. Then quick press button to toggle between Temperature settings #1= 1 Solid Red light, #2= 2-lights , setting #3= 3-lights. Charging indicator is blinking blue as progress bar 1,2,3. Drained at one blinking light, half charged at 2 blinking lights, Fully charged at 3 Solid Blue Lights (stops blinking). When the unit is drained it will power off. If you click the start button it will power on to red light then flashing blue before powering off to indicate needs Charging. Did I mention how much I love these guys on a personal level and how much piece and comfort they bring, knowing they are portable warmth on the go. Adjustable for indoors, outdoors, and a moving variety of both in Bone Chilling Arctic like Chicagoland Cold. And they work as advertised, as needed No B.S. / Hassle Free 😑. As a last note. Yesterday I accidentally 🙃 dropped one from about waistband high onto hard concrete floor with a dry Thud!!!! Immediately tested it and it started and operated like a charm. Good endurance. This before I took my review pictures 📸 so check em out. Rugged and Road-Worthy little guys. Also the product boxes have turned out to be excellent road cases, for my 2 sets. They fit really snug and have a clear cover inner box and outer shell with the graphics. Fit great in backpack. I even use the white plastic covers, for extra protection.
