Sorry i forgot to answer your question - I have some zoom lenses. Most are too big to use on the EOS-M, but I will use just for fun. I also have the 18-55 EF-M kit. I think the only reason the kit zoom is good is for its size. I find myself not using it because it has a boring focal length range, and its quite slow, especially at the long end. Its good to turn the camera into a high quality P&S equivalent, and it is very sharp images for a kit zoom, but it is not very fun to use.
