I had to break the Zefal off one of my bikes as I had installed it too tight and could not get it to open. It took a lot of work. Obviously, I cared about marring the paint on the seat tube or otherwise damaging the bike. I imagine if someone did not care about the bike and used a large wrench such as those designed to take apart old plumbing and the like, they could make quick work of the Zefal.
In my mind, this serves as no demerit for the product. In order for the Zefal to withstand heavy duty tools, it would have to be significantly more large and heavy. No one would want to use it. Zefals are intended to stop opportunistic thieves from grabbing saddles and seat posts and wheels off bikes parked in public areas. Bikes left outside overnight or parked in less trafficked areas allow thieves with heavier tools the time and privacy needed to defeat the Zefal. You are probably lucky they did not cut your lock and take the whole bike.
