All I had to do was plug it in to get traffic info. I live in Birmingham, AL. So far, I haven't used it during some of the worst traffic. I have noticed it won't report "congestion" (your typical 5 o'clock slowness) but only atypical delays, so just be aware of that. Otherwise its fine.
I went to Atlanta today where they have much worse traffic. On the way home, cars started to slow and I could see impending bumper to bumper traffic ahead. At that moment, the GPS alerted me there was traffic ahead and I had to option to chose a faster route. I got off at the next exit as advised. On the overhead bridge, I could see the others in traffic as I continued to make my way along a clear route. I'm convinced.
As far as picking up a signal, I only lost a signal once during the most remote part of I-20 for about 15 mins, otherwise it was "green" the entire time.
It can be a little finicky getting it to work with the GPS, you just have to do everything in the correct order. By this I mean, the traffic receiver must be plugged in before you turn on the GPS. Sometimes it will work if you do this out of order, but it is easier to just plug it in first.
I drive in Atlanta traffic every day and it provides accurate traffic data that is usually correct within a minute or three of what it displays. It also uses this data to update your estimated arrival time, which is very nice, though not a feature I use often. No issues with dropped signals so far when in the city, but don't expect it to pick up traffic if you live way outside the city. In my book, you can't ask for much more than that with a free service. I also like that it doesn't pop up ads like the Garmin traffic does.
Install is easy with the adjustable suction cups. The actually brain of the unit has a fixed suction cup and there are three more slidable suction cups on the cord leading to the antenna. Not the most attractive thing to have installed in your car, but you can get it tucked up pretty well in the recesses of your windshield.
The product was shipped quickly and included a photo copy of instructions from a TomTom manual on how to make sure the device is configured properly. This info should already be in your manual, but is a nice addition if you have lost yours. I wasn't expecting the suction cups (sorry, I have low standards for products), so that was a nice addition as well.
Things I don't like about the unit:
1) You have to make sure you get the PIN all the way in; mine has a slight tendency to feel like it's set when it's really not. Not a dealbreaker for me, just a minor annoyance.
2) The plug is a straight plug, not a right angle like the USB plug for the power. This means I have to set the Tom Tom about an inch higher on the windshield than I would like so the cable doesn't interfere with the dash. Again, not a dealbreaker; I'll probably buy a gooseneck mounting clip to avoid the problem entirely.
I've found that the traffic reports in my area are inaccurate more often than not. For example, on a recent Saturday morning I drove 45 miles to visit a friend. The traffic report indicated a construction delay. There was indeed construction, but the construction was in a slightly different location than the device indicated, and there was no delay. The device also indicated an accident with a delay. As I drove by the location, I saw neither accident nor delay; the traffic was typical light early weekend traffic. I got a third report of a delay on my way home. The device indicated a delay when the traffic was still moving at the speed limit. The unit gave the all clear indication just as we got to the residual backup from a cleared accident. So, I think the reports are best used as a warning that I should turn on the radio and listen to the local traffic report to find out what's really going on. Tom Tom doesn't control the local traffic service, so I don't consider the problem a failing of either Tom Tom or the receiver design.
