Bests & Worsts Reviews from Amazon

You can make these work, but there are HUGE security and usability problems. While this product is branded "iSelector", the actual manufacturer is not identified on the product or packaging. If you have trouble, you are invited to email merry_go88@163.com. 163.com is written entirely in Chinese, with no English information about the company. To use the device, you must install an app called "Jimvoo Smart" , which is put out by an individual rather than by a company. Are you willing to trust Ping Kwong Yip with complete access to your home Wi-Fi network? By installing this product from an unidentified company and giving access to your network to an unknown individual in China, you are risking your computers and possibly becoming a vector for internet hacks. Using the Jinvoo app, I added a device fairly easily, but it was given a name in Chinese. After adding three devices and giving them English names, I tried to group then to control them together. But, the app could not properly create a group. When editing group members, only two of the three devices would be listed as available to be grouped. That is when I realized that there is absolutely no support for this product. I did not get around to making work with Alexa, because the security problems alone prevent me from keeping the devices. Amazon should NOT be selling devices which need unfettered access to home Wi-Fi network unless they are backed by a reputable organization with a US presence.
