### 5/5 — It feels good‌ ​     ‍‌

*2023-06-28*

### 5/5 — Give the team thumb up  ‍ ‍   ‍

*2023-06-27*

The BMS Reset function in the TopScan app is incredibly useful for maintaining my car's battery health. It allows me to reset the battery management system, ensuring accurate monitoring of battery status and optimizing battery performance. It's a simple yet effective way to prolong battery life.‌ ‍​‌

### 4/5 — Capable Bluetooth Scan Tool

*2023-06-27*

I was sent this Portable Scan Tool to be part of the Beta Testing Program. Improvements have been happening rather regularly. This is a very capable device for a small portable Bluetooth Scanner. Well worth the initial cost is you work on any automobile. Downsides is there is a yearly subscription cost in order to update the software. Currently there is no dedicated iPad Version (Current version is an expanded iPhone Version). I also own the XTOOL A30M and feel that scan tool is far superior in user interface, capabilities, has a dedicated iPad Version & software updates are Free for life of the tool. I did give this tool a 4 Star Rating as per it has its place in the marketplace & No scan tool is 100% capable so you definitely need more than one scan tool in your toolbox.
