I have been using American tourister travel bags and laptop bags from quiet a long time and I never had any problem related to it.
But one thing I want to add is the quality is not that fine as other brands. But they are not very expensive as in anyone can easily buy them. Though tgey does't las for long if u travel a lot like me. I have been using two bags right now and the only thing I dont like abt them is bad quality of cloth. Please do improve the quality other then this its a gud brand and very reasonable too.
