If you are looking for a mid range satnav to get you from A-Z then you cant go wrong with this, it does everything that most newer high-end satnavs do, expected time arrival, options for fastest route or shortest distance (a nice feature is this is done on 2 slide bar scales so you dont need just to pick one or the other), tells you what lane to get into, tells you about saftey (speed) cameras etc You can also update your maps free online (disc and usb wire included).
For the price it gets 5 out of 5, however at this price you expect to give up some functions or quality, 2 of the only ones I can see worth listing are, it only has one voice that can sound a little robotic and not as clear as my previous Satnav (no fun downloading Billy Connolly etc) and the only way to control volume is by the touch screen. The speaker isnt the best quality so you may find your self playing with the volume more often, inparticular moving from town to motorway driving, of course this could be dangerous.
