Much better for not a penny

I find that its price is exorbitant compared to services and the quality of the product, the greater the need to pay a fee for the right to use a device you not pay off 100.
It certainly has additional functions compared to the competition but this is not enough to convince me, I call these "gadgets". It does its job like asking, although sometimes a bit random on speed and real-time estimate.
For 90 small detailed documentation would not have been refused, we are obliged to go to their website to learn about the features of the product (and those who do not have the internet or so limit?).
There is still easy to learn, but I much prefer him competition and even some free applications just as full and really profitable for motorists making a lot of road.

There is better elsewhere I think I pass my way.
