Just don't buy the cheap stuff if you plan to use it on a regular basis. The wheels fall off, the handles stop working, and if the zippers don't work, better hope you have duck tape. I have been through all these problems. For now, I have my Hartman stuff, but I guess others would say it is too heavy, but I do love it, because zippers work, and if it goes bad I just send it off and they fix it.
