<tutorial>
The first stage of using 51Degrees device detection in MVC is creating
a model. This Device model can access the Match object in two ways:
<h3>Accessing the Match object directly</h3>
<p>
This is the most efficient method as it returns the requested property
directly from the Match object
</p>
<h3>Reflecting the Match object properties</h3>
<p>
This uses reflection to set all the properties of the Device object, so with a large number of properties
will be a less efficient method.
