My towing mirrors have rubber bands which sit over the Kia mirror and these hold them in place. Well, almost - the nearside one does tend to move a bit.
Although I've only towed my van (Bailey Indiana) once with the Sorento I'd make the following comments; the van is 2.28 metres wide & with the Sorento mirrors alone I can easily see down both sides of the van, however as I'd already got a pair of Milenco Aero's I put them on anyway, The mirrors are rock solid (as they were when fitted onto the Audi A4) & what a view behind the van.....fan bl**dy tastic! Most definately the ideal combination!!!!!!!
I use Milencos ona Sorento and they are rock steady. I can see behind without mirrors but boy do they really improve your view. The Milencos don't need bands on the Sorento as the screw clamps tighten in such a way that you would have to tear the car's mirror off of its mounting rather than the Milenco give way. Milenco say that for most vehicles the clamps are all that is required.
Iv'e had a set of Milencos for a few years now but stopped using them in favour of the "suck it and see" type.
Reasons - the little rubber caps on the screw clamps were always falling off and getting lost and the mirror silvering was spotting; they were also a bit fiddly to fit and line up.
The suction cap type by contrast fits in seconds and moves with the mirror so lining up is as easy as lining up the cars own mirror i.e. manually or electrically from within the car.
I have used them for two seasons now - they are stable, have never loosened or shown any sign of falling off, give as good or better view than the mileniums, in spite of having a smaller mirror and store very easily when not in use in their own drawstring bag.
A wonderful invention which indeed does what it says on the tin!
When they are in place you tend to concentrate on the view via the additional mirror and ignore the original mirror which I found is the same case as using a strap on.
