How do you know when these are all heated up and ready to use? I don't see an indicator.

You can either touch the plastic cover or I usually just lightly touch one of the actual rollers. Once I pick one out of the container, it normally cools down around the edges rapidly quick. I've had mine for over two years and I've never burned myself!

You can tell they are heated by touch. They become very warm so you can pull a curler out & test for warmth. 10-15 min & they are ready to go. These are very hot so you will have to handle lightly while rolling but they do the job. I have long hair & these hot rollers create beautiful curls.

Don't know for sure, mine are on, I actually cover them with electrical tape when the units are visible. Must not be working.

I'll check with a thermometer later but it should be warm enough to notice. Also, it takes a few minutes to get rolling. I would suggest flipping the heat switch on and off about half a dozen times; the contacts may be oxidized if it was shipped through a moist location. Simply opening and closing the switch may be enough. I had the same trouble recently with some surge suppressors.

You leave them in the red case just like you received them, and plug them in until they're heated through, about 10+ minutes.

I've never seen mine glowing red and the 8 min warm up is normal. Enjoy grilling

You can't tell if they have absorbed all the water they can by feeling them. In fact there is no way to know when these are full. Once in awhile, put them in an oven set at 110 -130 Deg F for an hour or two. I use them along with a little bit larger metal pack that has a small window with a material in it that changes color when it gets wet. Then I pull them all out and dry them at the same time. Unless the container is really moisture tight, they don't last near as long between recharges as you might think. The larger the container the more you need and it may take more than you think to last very long too. You can't tell if they have absorbed all the water they can by feeling them.

We cook them for a few minutes longer than the box says, then check them every 2-3 minutes. Once they start to look kinda done, start poking one with a tooth pick each time you check them. When the tooth pick comes out clean, they're done!

They are instant on. I'm using them in track lights and they do not need to heat up.

Not sure but make sure it's turn on and the light came on to let you know it's ready for usage

5-6hrs. Depending on temp I guess. They do heat up when in use. Use units for a quick 10-20% charge if need.

no, the lights just show that power is on and that the thermostat is cycling. its not useful other than saying its 'working ok'.to cook, you have to time it. that's all there is; there is no way around it. you watch for steam and you time it and learn what the time is for your batter.

I do not. I cook them and once the timer goes off leave them set for 2 to 5 min in the machine still covered. Come out perfect.

I honestly don't know. I purchased all individual units. I would think that both units would heat up so it might not be a good idea to leave one empty.

There is a book with directions but it's fairly straight forward. Plug in the unit to the blanket. Run the wires under the bed to the area where the controllers are needed. Push the one on the left. It will say L for Low. Push again for higher settings. Push the one on the right to use the Pre-heat setting. You'll know within 5 minutes if it's heating up.

There is a small disk that can barely be seen in the photo, you simply snap the disk and the entire pack will begin to crystallize. That is how it heats, it is a self heating pack. To get them to go back to a liquid state you boil them in water for 15 minutes and you can then use them over and over again.

Just pinch the penny like object inside it to begin the chemical reaction. They get warm in 5 seconds

If it's been in the freezer I has to thaw out first. Then put in microwave and whaalaa it's ready and heated. Heating depends on your microwave wattage so look on the package.
