Very nice features... Is fire one of those?

I really wanted to add a smart plug that would be able to handle a space heater so I opted for this device made by a company called Aishlilia, I know catchy right. Seriously these little Chinese companies need to hold a focus group before they settle on a name.  This is an in depth review, I hope you can all hang in there.
First off I love the how this device monitors power usage. It's not perfect though. The mA and Wattage is pretty much spot on but the voltage reads very low under load for some reason.  The KW/h is pretty close and you can easily tell about how much that device costs to run just by multiplying the KW/h by the going rate for your region.  For me KCP&L currently charges around $0.10 per KW/h so this space heater cost me around 29 cents to run to run for about 2.5 hours, I ran this space heater quite a bit to get this test finished.

This device should be able to help the consumer quantify just how much things actually cost to run and this is one of the hardest things to teach my customers.  I only wish there was a spot to input an average price per KW/h so the software could make all the calculations.


My main concern came when I used a space heater on low (6 amps) in my garage and noticed it was heating up. I decided to look closer at this issue. For this test I used the space heater on high (about 12 amps) for about 30 minutes and took a before and after photo with my Seek thermal camera. As you can see it topped out about 104f (40c) this is up from the testing temp of about 70f (21c) making a pretty strong rise in temperature, especially since this test only lasted about 30 minutes. Plastic doesn't melt until around 200f (93c) so this isn't in danger territory yet but since this device isn't actually UL listed it does pose a slight to moderate risk.

After 12 Amps for about 30 Minutes
I will continue using this device through the winter since I think it's safe but I have to bring this up because I think companies need to take these kind of things important.

The UL listing is an added expense for sure.  I mean this testing could cost upwards of $30k initially and they have to pay a good amount to maintain it regularly.  I can see why companies are avoiding this added cost but if they would spend this extra time and money they would be considered far more reputable and they would open themselves up to getting in some of the big stores like Lowe's, Home Depot, and heck this device would even do well in Wal-Mart.
What do you think? 
How important is a UL listing to you? 
Would you use this device? 
Would you be willing to pay a bit more for a device that's been tested safe by UL?
