I bought this to use as a stand alone unit. My wife preferred its appearance in comparison to the cheaper looking models. I cannot vouch for the Geeklink system and if it is better in their ecosystem, but I did not want to set up an account. The quality of the design was an issue. What I had to do to get good results: 1.) The PMI values out of the unit were high at the start. This settled down after use, I am guessing that was latent particulates from manufacturing. 2.) The touch sensor did not work well on my product. I took it apart and found that the PMS 5003 detector case was messing with the capacitance of the touch circuit. I had to cut the solder joint tip flush and add resistance with plastic bags and electrical tape between the touch sensor and PMS case. Now it works fine. 3.) If you are going to use it as stand alone remove the WiFi module. Without the WiFi module it defaults to pretending its connected and it removes the connecting screen. Good job firmware guys! 4.) The speaker was obnoxious to me so I added a little tape over it to muffle it. That is a personal preference no points deducted :)
