Flawless temperature preservation, easy handling, the food comes out very tasty, if the networking has been done correctly and you have registered in your account, it has the ability for remote control. This is extremely useful if someone is cooking and suddenly there is a power outage and they want to reset it (see case 2 below).

The reason I gave it a 3/5 instead of 5/5 is because of the following 2 issues that bothered me:
1. Difficult networking: Instead of the device scanning and seeing the available Wi-Fi networks and connecting on its own by entering the passwords, just like printers do, utilizing the router's UPnP, it requires an additional device, either Android or iOS, to control it through the application. For those who try it, persist a little longer. It may not seem to work, but it will eventually. Also, on the first attempt, bring it next to the router only for networking purposes. From the next times and onwards, it won't be necessary, even if it's on the other side of the house, it will be automatically connected. Cheaper devices have simpler networking.
2. In case of a power outage, if it was set to count down, it completely loses track of where it left off. So, if there is no UPS for this and a UPS for the router, it needs to be checked for the time, so that after the power outage, the correct time is set. We won't get a UPS for every electrical device we buy, nor do we live in a futuristic capital where all houses have a basement with UPS. Somewhere, they should fix this.
