I think this may be my first deal post, so flame away if I screw up. I noticed these have dropped in price since I purchased mine in December, and I noticed that they are a better deal than almost any of the other wifi plugs that been posted in a while, so I figured I'd post them up for others to see. I have 5 of them running in my house, almost all have been running various electric heaters over the winter (on low, so about 500-700watts) , and have worked like champs. I chose these because they are rated to 15A, don't need a hub (I use the Smart Life app for all of them), have energy monitoring circuitry (so I can tell if the heater is running or not) and they are low profile enough that 2 of them could fit on the same outlet plate. One did die shortly after receiving it, but the seller replaced it quickly with a 2pk, which is why I ended up with 5 of them. Not UL certified as far as I can tell, so this is a negative, but they've worked great thus far, barely feel warm after hours of running.
