I had a Brultech and a TED5000. Now I have a Sense. The Sense is by far the best one I've used. It's super easy to install, only has 2 CT clamps (unless you have solar, then it has 4), and the app is well designed and useful. The other products had a bunch more CT clamps, and in the case of the Brultech, a terrible windows app for collecting the data and storing it in a database that would routinely fill up and become useless.
That Curb thing looks neat, but that's a lot of CT's to install.
