Bought this as it seemed good value and the original TomTom in-car lead had broken off at the connector. The in-house charger is definitely useful as the TomTom seems to drain its battery even while switched off, so a periodic top-up helps. The in-car cable works fine but is too short for my car - the cigarette-lighter plug is behind the handbrake - so the coiled cable acts as a spring, occasionally catapulting the TomTom onto the passenger seat. I suspect that as the cable ages it will get less springy ...
