It could be very good for the price, but unfortunately the app does not start on older phones like the Samsung Galaxy S8 and Note 8, it's sure to work on the S20! This was not mentioned anywhere in the description and it's a huge disappointment. This needs to be considered before purchasing because without the phone software, its capabilities are very limited. It would also have been good if there was a battery discharge option included. Due to the fault of the phone application, I can only give two stars. Otherwise, it would deserve five for this price.
