I bought the SD-425 as an upgrade to my SD-400S primarily so that I could use 2 collars simultaneously and still have a tone without a shock option. So far the system works great and I am happy to have the second collar - much to the dismay of my female dog who obeyed when convenient. Now she is an angel! This collar is definitely the one to get if you want to add additional collars to the system.
