Other: If you are looking a very cheap and ready to use gps for arduino, this is the one!

Pros: Cheap Easy to get started Small Works perfect with my arduino uno via serial (4800baud).

Cons: Slow start up Says i'm 15 km away from my actual position and it says it has perfect GPS reading (Only me?). Boring packaging, only a bag. Don't listen to my nmea commands.

Other: Worth the money. But i am disappointed on the precision of the unit. And it would be nice to have a nicer packaging. Perfect for measuring speed.

Pros: Great device

Cons: None

Other: Buy it!

Pros: This unit has a very fast signal acquisition time. The power consumption is low, making it ideal for battery powered projects. The serial communication protocol is widely available on the web, which makes it easy to use.

Cons: Loses signal at times when inside a vehicle due to the directional antenna that needs to be facing the sky for best signal

Other: A better GPS module can't be found for this price
