I've not used the EMek but a friend of mine had the eNMEy and it leaked air on only his second time using it. He changed it to the Maxxed and not had any issues with it so far. I've personally got the 2011 rail which is the more basic version of the maxxed and not had any issues either. It's pretty reliable and basic so a good starting out marker for your first time. If it's your first item to get though, I would recommend buying a decent set of goggles / mask firstly however as rental ones really are bad!
