Review: Worked Great, Easy to setup - The SL400 worked great, right out of the box. There was a software CD in the package, but I had already downloaded the software for the unit. Selecting the proper standards was easy, and we were up an running in minutes.
Review: Good product, could use some added features. - Use this product in a community hall to monitor sound levels of bands and DJ's. Does a good job recording sound levels over time. The downloadable files provide a nice Excel spreadsheet graph. I dislike the fact that the meter cannot be set to start recording at a future time and stop at a future time. I dislike that a new 9V battery only last 18 hours.
