Yes, make sure that it's in heat mode and that the temperature nob is turned in the proper position. Then, you'll feel heat. really good heat.

Yes. Turning the knob up...over the temp in the room...turns it on. Works very well!

Yes. There is an automatic eye with settings of 30 or 60 seconds. There is a manual option on the switch that allows the on/off button to work.

Should not matter but normally I turn it on and don't turn it off right away. It does come on quite bright.

No, but make sure you put it on right the first time because it sticks on right away

No, the light comes on when you turn it on. I love it. It is very sensitive, no worries about knocking it over, it will cut off immediately.

It's pretty much "instant on" as it starts warming right away. At the most, 1 minute.

Yes, it will turn on automatically as long as you don't manually turn it off.

No, you can press the button to turn it on and off and it will still come on at the programmed time.

No it comes on rather quickly and bright. I use one in my basement and one in a upstairs bathroom.

It does go on quickly. The pressure from sitting on it holds it in place. I never had it on a moving vehicle. It is solid and works great.

Yes. Come on and then you can immediatly tap on the switch and it will go off. Works great!!

Really good but not immediate. We run ours overnight or for a few hours after cooking strong smelling things and it works really well. It also helps to have it on while cooking.

Yes it does. and Switches of automatically if not used doe more that 5 minutes.

I don't think it's "instant", but within a minute I would guess. I have not tried it.

No. All devices controlled by the master device turn on immediately. There appears to be no delay.

It's on as soon as you plug in power. Just take the little rubber lense cap off.

It does have about a 2 sec delay before it will turn on or off. I hope that helps.
