DO NOT BUY!!! They released ambur 2.0 on Monday which is completely a junk. None of my computer can connect to Hub, cause huge problem for the restaurant. Called ambur so many times nobody will answer the phone, all they do just tell us on their blog is the fixed version has been send to Apple. Really? Until Friday still not fix . Unbelievable, how can you do that to your customers. We have hundreds of hunger customers come to the door. Do you know how angry they are if they can not get their food on time? Shame on you
