First one came with the USB charging port on the receiver loose. It was hard to get to charge - had to wiggle and place the cord just so... then (after 5 days) it never stopped charging (a short perhaps... no idea). Returning that one now and ordering another in the hopes that it was a fluke. 3 Stars because it looked like a solid setup if this particular unit hadn't been defective. Let's hope the next isn't the same. That one will get it's own review. 1 if it turns out to also be defective, or a higher score if it is in perfect working condition right out of the box.

Muy bueno, en modo PPP en sitios despejados registra una precisión de 18 mm. Claro que se toma su tiempo para dar solución fija sin usar base.
