Ok, so I've been coming here for about 2 weeks or so now. One thing I've learned is that there is only one person who actually knows how to do their job. The rest either have a base knowledge of the equipment or just know how to push buttons. After a week, you should be able to operate the machines on your own and I do not have anything bad to say about their functioning properly. This place can be pretty pricey though.
Oh, and do not be surprised if you come in and the appointment you set the day before is gone. This is a frequent occurence here.
