Summary
Setting up and using a Bluetooth OBD2 adapter is easy to do with a smartphone or laptop.

There are some technicalities involved that will not be hard for most.

If you have ever installed an app and paired a Bluetooth device before then, you will be reading and clearing codes quickly and easily.

The Bluetooth dongles shown here are mainly for the average home user or back-yard mechanic.

A busy mechanic shop will no doubt need more robust tools that can take a daily beating and rough environment.

The above scan tools will benefit mainly any home user who has an engine light on and want to know what the error is.

Since most cars and trucks only give a vague engine light for any problem, a user who has these tools can make them invaluable for saving money.

For example, some codes are a simple fix, such as a bad gas cap which can make the engine light come on.

Even if the problem is beyond the ability of the user to fix it will give them more information needed as to the problem and average repair cost.

For example, if an error code is given for a bad oxygen sensor, then reading through forums about the vehicle and what others paid will help keep a mechanic honest when they work on the car.
