I like how easy it makes entering data for daily entries (e-mail reminders). This program really helps with managing our chemicals! It's difficult at times figuring out what information needs entered into this system but we are getting there!! There isn't anything negative about using CSEMS or any of their products in general - just make sure once hired as well have someone who knows exactly where everything goes so they can assist if needed. We're able enter all required info without having anyone else touch what was previously created by another employee/customer service rep etc..
