Quick Electric DMM USB Heating Pad Heater Keep Warmer Rod Stick Indicator

I too thought this thing was worthless as I have tried 2 other heat rods before, BUT THAT WAS UNTIL I FOUND OUT THE TRICK. This heat rod warms ITSELF up fairly well, but the material around it cannot sustain that heat very long because its most likely TPE plastic you're using it on, but LUBE DOES. Put in the lube first, THEN use the warmer, the heat will transfer to the lube which will hold inside, and then evenly transfer to the material. The problem is with no lube most of the surface area is just touching air which is a terrible heat conductor. So you use liquids to make up for that.

It only lasted for a couple months. I probably used it 10 times. Definitely don't get the cheapest one of these. I will likely spend double if I buy one of these items again.

came in a busted box and the item itself had no wrapping, just loose in a box. kinda concerning but it does what it says.

Cheap

pros: it warms up real good, too good in fact it gets pretty hotcons: it never shuts off to cool down so you have to unplug itthe only reason i gave it a 4 star is because it has than little hole by the ring it says its waterproof but that dont look waterproof to me in other case its perfect for heating up certain things it does get pretty toasty otherwise

This does what it is supposed to do, but be careful, this gets HOT if you leave it in too long. Put a finger in before anything else to see how hot it is inside. Would buy again.

Yes it does the job your hoping it does perfectly lol

Just got the product, plugged it in, I see the blue light, it never heats up even after some time. I believe I got a defective one. However for this price I don’t think I’m going to suffer the embarrassment of handing it to an Amazon employee to bag up and return so uh, guess I’ll just toss it.
