I am very satisfied with this NVR model N882A63B which I purchased on the Lorex online store in February 2021. The delivery was fast and the unit was well packaged with no damage. Setup was very easy. I bought my first NVR from the Lorex online store in 2018 and came back as a repeat customer. I have used customer support in the past and that works very well. My call was answered quickly with no wait time and the service was perfect. Overall I have had complete satisfaction with the online store, the NVR unit and the customer support. Also, my purchase in 2018 included six 4K 8MP IP outdoor cameras that have run 24/7 with no down time.
