Listed size is perfect: small enough to not be cumbersome or heavy, but large enough to be readable.
GPS reception / sensitivity: good
Very easy and intuitive enough for use.
The screen lacks a bit of brightness but it is the price to pay for a good autonomy.
The touch screen 2.6 '' is sensitive (works even with gloves).
Tested sealing in the rain: ok.
Quoted fare I took in an offer incorporating silicone protection and a handlebar clamp. The price of the set is rather well positioned to compete. Nevertheless this type of device still remains generally expensive.
Where the bat starts to hurt is when we add funds to the cards themselves are unfortunately prohibitive (over 300 for the whole of France) despite a good quality and a high level of detail (origin IGN).
In short: a very good camera that gives me satisfaction yet.
