Useful tool rather than a bells and whistles gadget.
I'm not sure this is something for people who want to speed and avoid cameras/lasers etc, but it is for someone who wants to drive within the speed limit and wants to avoid getting caught out on the odd, unlucky occasion he has crept above the limit.
There is a real benefit, in my view, for buying a single or dual function device rather than one which attempts to d everything. This unit has a large display which allows you to clock the information using peripheral vision, or very slight movement, and since the information is mainly only the current speed limit plus your current speed it is easy to keep tabs on. The centre circle activates when a trap is coming up.
The visual and audible warnings are about as good as they can be, and plenty good enough.
As far as speed limit accuracy goes, it is pretty much spot on for main roads and most minor roads. Be prepared for it to get it wrong sometimes on the country lanes. At first I thought that was a key failure, but as it happens using the unit conditions you to watch more acutely for the speed limit anyway.
The unit picked up high risk zones regularly and noticed me of cameras I did not know existed on routes I drive quite often, so very useful.
The only real downside to an otherwise well designed unit is the speaker quality. At full volume there is so much distortion one can hardy make out what is being said. It lets the unit down, and I would have thought there is no real excuse for it. However, dial down the volume a bit and it gets better, though hardly what one would call clear audio quality.
However, as this seems to be a common complaint with units of this type, regardless of brand, I guess it something one needs to get used to if one is going to ue one of these things.
