Toad AI606 would be the one I would go for imo.

Had them on four of my cars now and just about to put one one my current car.

Not had one problem with any of them!!

The Clifford I had on my series 2 on the other hand, I thought personally was crap compared to the Toad.

Always going off, wouldnt disarm nearly everytime I went to a petrol station, would lock the doors automatically even if you didnt want it to etc.....

Wouldnt touch another one again personally.
