I was able to turn it on. However it failed to measure anything via clamp (no current or voltage). Really deserves 0 starts. Clearly broken products even though package contained multiple QA stamps of approval in Chinese and English. I guess I should not expect too much for $27. On and off switch worked (it probably qualifies for working product in China)

I like the temp guages but my truck has a dummy light for the generator. It's great to be able to monitor voltage output without installing a gauge.

I un-boxed it. I pluged it in. I turned it on. It stopped. I diagnosed the problem. Blown fuse. Back it went the next day.

I flicked it on and it didn't light up. If I press it really hard it turns on but as soon as I take the pressure off it goes off.

I went to take it apart to fix it but has a triangular screw >_<

I installed unit turned it on it lit up nice and bright, then there was a pop,light went about half brightness and flickered. Returned unit replacement arrived a couple days later, but I had to re install I guess faulty items can happen.

This is pretty cool, I hot glued some LED red lights to the back with a timer. Turn it on at night looks real cool.

And there was light....  Had an old fancy florescent light in the kitchen....  It had 2 ballasts and they both went out...  It was going to cost 75+ just to replace the ballasts...  I never had dealt with LED's before, but I liked the specifications and the reviews...  It was very easy to install and wire up to the existing outlet box....  I hit the switch and there was light....  Super Bright Light...  It is much brighter then the 4 foot 4 bulb light florescent light that we had up there...  And it only uses 26 watts....

Light bulb would turn on.  Unfortunately, the motion sensor didn't turn on or off the light bulb.

May be small, but would not want to get hit with the spark this thing puts outs! When I got it, it showed power, but the LED did not work, and pushing the button to test, did not work. Plugged it in for 6 hours, works perfect. I turned it on and pushed the button to test, and this thing made me jump LOL I work at night and in the past I have had problems, I checked with my state first for laws and was good to go. I hope I never have to use it, but if I do, Not worried about it working! I would recommend for both men and women.

Caught on FIRE!  I'm a master electrician.  I wired it properly.  I was testing before I crawled into the attic

the lights on this never came on so i don't know if it ever worked. but my TV and wireless router were blown out just this week. no marks on this thing so i think it just passed thru to my equipment.

after installing your new glow plugs I also rewired the glow plug circuit with a  totally separate solenoid and wiring to the new plugs.
i decided to go from the battery with the new circuit .I tested the old circuit and only had 7.5 volts (just not enough)now I have 12.6 volts  WOW ,WOW,WOW it starts GRE888888888

Star arrived today.  Put it on tree and plugged it in.  It came on briefly, then went dark.  Everything looks fine, but it won't light.

I connected it, the light came on but the device did not work! I ended up using my car battery.
Am I supposed to connect it and wait for a while? I have not tried doing this.

turned it on and started to heat up right away, so i put it in my tank and felt it was starting to make the water warm. When i came home that night, the water was cold, even though the light was on and it was plugged in. Returning.
