### 5/5 — Convenient app

### 5/5 — BT connection is Buggy

*2019-09-27*

You would think that it will make your job easier??? Right? No..., It makes it harder!!! it disconnects and shows on screen CN ER... 
now you have to climb the top of the Bus AC unit to on/off again.....and it takes a While to Reboot...
The older Jb, CPS works fine, Just press a button and it will show Vacuum reading in Seconds. 
I bought and spend money to make my job easier and it made my Job harder... 
thought it was a good old made in USA company and they will make a product that will work.... 
but No Sir the Girl just transfers you to VM when you call for help???
I am been working on bus AC for 20+ years and it’s getting harder to climb the ladder to check vac reading so went and bought this tool and now the darn thing is making it more frustrating...
If You read this return this JB BT!

### 1/5 — Buggy.

*2018-03-30*

App keeps crashing. 
Even when it works, it loses connection. 
If you’re lucky, it’ll maintain connection till the phone display sleeps then it immediately disconnects. 
Even though the Bluetooth is still connected, the app just says disconnected. 
Once it says disconnected it will not reconnect, and scanning will not work either. 
It simply will never work until you hard reset the app and start over, but you loose all your data and progress for that job. 
This would be a great tool if only the user interface were reliable.
