Randomly Turn Off and On
590068
Unfortunately, they don't seem to work with the halogen track lighting in my kitchen. Very bummed. Light is a bit whiter, not a typical LED bright white, but they are clearly noticeable when compared side by side to the halogen bulbs.  Problem is they turn off randomly for 30 - 60 seconds, then turn on again.  I've tried every bulb and every light fixture in the track, and they all blink.  I've read that some LED's are not compatible with certain transformers used in halogen lighting. I don't know if it's a manufacturing issue, or a technical one. But, these won't do for me.

Set'n Forget if you don't want your food to cook... This unit constantly turns off for no reason, you have to check it every 20 minutes to make sure It did not turn off. This is unacceptable behavior for a device that is supposed to let you cook food unattended.

Have some problems on and off with power on.  Sometimes the power turned off if not select the input source within 5 seconds.  It's OK for casual use.

If the TV is on, or I am playing music it seem to go off. I use it only occasionally, and mostly keep the battery disengaged so I don't traumatize my dogs.

It keeps turning off every 2 min or so.
I have to keep pressing the button for it to charge.

It does things you like, but turns off when you least expect it.

Great reception and versality, but has a built in 1-hour timer I can't figure out how to disable permanently.  So I hardly use it anymore. Wanted it for talk shows to lull me to sleep but suddenly it shuts off, and then I wake up (old habit).  Frustrating!  I'd give it 5 stars if it didn't try to out-think my lifestyle!  Auto-shutoff should be a user option, not a standard one.

This camera randomly turns on and off. The wiring is not defective the monitor is. It worked fine until 2 weeks ago. Highly disappointed.

Except...

They like to randomly turn on when not touched. Which is kinda annoying when you're trying to sleep.

I have had it for 4 months. Everything was good until recently it plays drum even when I am not pressings the drum sensor. It just plays again and again until I turn it off from last page. Three stars for the on and off switch!

No OFF button.  It's a calculator with a quality name. can't believe it has to shut itself off when it wants to.
