This is a great unit for your money. It was exactly what I needed. It had all the features I was looking for but they are not difficult to operate. It is easy to assemble and doesn't take long to set up at all. We were able to get very good video quality. Overall, we're happy with it. My brother ended up buying one too.

Pros: Easy to setup. Clear recording based on quality of camera used. Records continuously. Good for the price. Cons: Does not record sequentially or view sequentially. Only view in quad or individual channel. I prefer a larger drive. Had to go onto internet to find how to set it as a master vs a slave drive. Since it will only record set as a master, a master setting should have been the default.
