Comments on MGS-400 for Android

★☆☆☆☆ Jonathan Burkholder · Jan 8, 2021
Worst app ever. Cannot connect it to the device and no tech support. Bacharach clearly wants out if tge business.
★☆☆☆☆ Curtis Bear · Aug 28, 2020
This app doesn't find their products. Avoid both the app and products. Also for those wondering the sensors are useless unless you can connect to the app. Stick with reliable companies for sensors folks.
