I also had this as the kit lens on my D7000. I didn't baby the camera and lens, but I don't treat it badly either. I think my major mistake was picking up the camera and lens by the lens, which I do not do any more, but I would have never thought that it would cause a problem either. In any case, this lens has a plastic (instead of metal) mount and that plastic broke and the lens will not attach to the camera any more. I bought a 50mm f1.8 and sent the 18-105 back to Nikon for repair (warranty). They would not cover it and called it physical damage. They wanted over $100 to fix it with the same plastic part. I decided not to get it fixed and found the part online for 10-15 bucks. I haven't ordered it yet, but I plan to try to fix it myself (video online). It takes very good pictures, but the construction quality is not great to say the least. If you end up getting it, make sure you're taking great care to never bump it or pick up your camera by the lens.
