Review on 🚗 Upgraded NEXAS Car Diagnostic with Protective Case | OBD2 Scanner Engine Reader Featuring Graphing Battery Test | Scan Tools for Check Engine Light Fault Code Reader with Freeze Frame Viewing | Enhanced Version by Eric Jones

It will work perfectly the first time and maybe even the second time. Then he turns back into a pumpkin. Tried to use it a third time, of course I needed it after the return policy expired for 2 days and it didn't work. He keeps telling me he has communication problems. Plug in the correct plug (there is only one plug that worked last time). The engine is on (no, the engine is off, just like last time). My computer may not be compatible (it's the same computer as last time). The only thing that works is the battery tester. Don't waste your time and money with this product. The only reason it has good reviews is because customers haven't bothered coming back to update their initial positive review.
