I like how user friendly the software is. It does what it says it will do, and nothing more. The customer support is also excellent! If you're looking for a simple tool that will keep your battery bank in good shape, this is the ticket. I have been using this product since they first came out with their "advanced" version. Their original version was great too, but they kept adding features and making things more complicated. That's not necessarily a bad thing; just make sure you know what you want. If you just need to run some basic tests on battery bank before installing it in a project, this will work. We were able to keep our battery banks in good health by running short checks every few days.
