The system has been very easy for me as I am not tech savvy at all! It's simple enough that even my mother can use it with little help from myself or anyone else in our family!! We have used this product several times now since we purchased ours back around March/April 2018 when they first came out into stores here locally near us.
There are no complaints about anything yet but like any other technology there will be growing pains along way if you don't know what your doing so make sure u get some training before using them yourself. You won;t regret getting one because honestly once installed its just something thats always close by where ever i go whether home work school etc..
