The product is easy to use and if the readings are really correct then it is extremely useful. I have seen in other reviews that the stickers and UL (Test for Safety) marking are missing. I can confirm that there are no stickers or labels regarding UL. As a result, I would not recommend continuous monitoring under high load. I used it up to 300 watts continuously without any problems. I will look for a replacement for safety reasons. So good for temporary use for sure, but be careful.
