Prior to this I had another brand, but for the entire time I had it, it often stopped working.  I paid twice to have someone come out and fix it... always more than $100.  

What I like about this one is that is takes a smaller footprint.  Instead of having two separate containers, both units are combined in one housing.  It’s easy to set up, works great, and you can get alerts on your phone.

I would recommend this in an instant.  Saved a lot of $$$ with this unit, and I can’t think of one thing negative to say about this unit.
