I’ve had a 9403 for two years (almost to the day). I use it at least once a week. It lives in the boot and gets used for short trips & long trips with one, two or three bikes. It’s easy to fit, secure once it’s on and easy to take off.
If I had to find fault there are two, nothing serious though.
i) putting a bike on alone is a bit of an art. You kind of need three hands – one to hold the bike and two to do the strap. It doesn’t take long to get theknack though.
ii) the tilt mechanism to get in the boot when it’s loaded has never really worked for me – either the catches doen’t undo properly or it’s difficult to tilt with three big bikes on.
All in all, if I lost mine tomorrow I’d buy another one without bothering to look at alternatives.
