Because of the more complicated design I think they should be treated with more respect than a standard binocular.
The fact that the button has to be held down is a nuisance, and for many that means that basically the binocular is supported with one hand.
One needs to be strong if using it for an extended period at one time.
A point of concern is how long the magnet/s last at full operational strength. I don't know the answer to that.
However, for resolution, I don't think that any hand held binocular can equal one.
As to repair costs, I suppose that as a percentage of the new price, there won't be much difference compared to another binocular.
The Canon IS binoculars have only a one or two year guarantee, I think.
One could take out a complete accident and repair insurance, but in my experience insurers try very hard not to pay, or find exclusions, unless one deals with a very top end insurer.
P.S.
The resolution was 6.5 arcseconds, compared to 8.5 arcseconds for the Canon 18x50IS, using double stars, so the comment about just 2x extra magnification is by someone who hasn't used both.
I see no point in tripod mounting binoculars for my type of binocular viewing.
If one buys a hand held IS binocular, the whole point is to dispense with a tripod.
I used a Japanese 20x80 Porro and a Soviet 20x60 specially hand made selected binocular for over a decade.
These were used hand held, but mostly braced on anything available.
But I was younger and stronger then.
Even now I have no trouble hand holding cheap 15x70s, although they are not robust, and may break if one coughs too much.
