First, personal GPS is not the cheaper the better. If a seller recommends
you a GPS location system with free maps for life at a ridiculously low price,
be careful.
Second, the functions are not always better. In terms of navigation, a
locator with simple functions is not worse than a full-featured navigator, on
the contrary, the performance of products with simpler functions is more
stable.
Third, sales do not equal quality. Although the sales volume can be used as
a basis, it is best to look at the evaluations made by buyers when buying this
product. The evaluations of buyers are generally more pertinent.
Fourth, functional support does not mean functional availability. Many
functions of GPS, such as mobile warning, can only be realized by accessories.
If GPS supports these functions, it can be used with accessories. If it does not
support it, it cannot be realized.
