A company that STANDS behind their product
Let me start by saying that I recommend this product not only for its features and quality but also for the outstanding customer support.First, with the product itself:It works as it should, its convenient and the smart features tie right into our Alexa ecosystem. No complaints and easy integration. Basically it does exactly what its supposed to and does it well.Now the support? In a single word…Amazing!Just about 14 months after I purchased this surge protector, it started power cycling and would not stay on. I contacted the Tessan support team and they asked for the description of the issue and a photo or video to show the issue. Once I provided all the information, they stood behind their product and shipped a new one as this issue should not have occurred, especially so soon after purchasing it.Going forward I will be a faithful customer based on their support alone. I’d rather purchase a product from a company I trust than to save a dollar or 2.

Almost perfect
Pros:* Very easy to pair as with most SmartLife ecosystem devices* So far working well manually and with automationCons:* Covers both outlets so would have been nice to have an optional screw for permanent installation on a standard outlet, or it could have been made slightly shorter on the top so you could still use the top outlet.* Would have preferred to be able to control the USB ports individually.* The lights are pretty bright/obnoxious, definitely could be dimmer and in colors that don’t affect night vision* Wish I could disable the energy usage tracking feature, not a fan…

Quit working after 8 months
This plug stopped working one day out of the blue after about eight months. It still can receive power, but the pairing light will not blink. I have done all the steps correctly and still cannot get it to go into pairing mode. Iâve been using smart plugs For about seven years. I know how to use them, but for some reason, this one just quit working.

Wow
Didnât know it would cost $40 a month to use this plug otherwise I would have bought something else. Works well but donât think you will be able to use it with your smart home unless you pay the price.
