They clearly make reference to the "on-off" button under the clear dome.

You have to pop off the clear dome and press the button to activate it then pop the clear cap back on.

Also, the plastic dome on the top is not easy to remove but probably shouldn't be in standard operation

While getting ready to leave a bad review I spotted one that said before you return it as broken, "pry off the clear plastic dome" and amazing, it works fine and it's now been several months of steady use

The "instructions" indicate you are supposed to push the blue button on top -- which is patently impossible, since the clear dome over it is non-removable

Just pop off the little clear dome and push the blue button to get back in business.

You got to pop the top plastic dome off with a knife and press the blue button

Also, if you replace the clear dome, it can be a challenge to remove again, requiring something to pry it loose with

I just leave it on now because the dome is on there pretty good...

I reset the trip button, put the dome back on and everything works

You have to remove the clear dome to access the on switch.

Make sure you remove the plastic dome and depress the button

you have to pop the clear dome and push the blue button

The blue light on top is under a clear dome which appeared to be non removable

The lighted on/off switch on the top of the unit is protected by a clear plastic dome, which requires some effort to remove (in my opinion, a tight cover is preferable to one that could fall off easily)

It would have been nice had the manufacturer added 2 simple things:a) an indention somewhere on the clear plastic dome to help signify that it's supposed to come offb) put an ON/OFF label near the button, or the symbols

Upon further inspection, you have to pry open the top clear plastic dome and click the small blue button to turn it on.

I took a chance & used a screwdriver to pop the clear dome off & sure enough the blue button under it is the trip button

so I could plug in a Kill-o-watt at a nice angle for viewing
