I purchased these 3 cameras from BestBuy to use while we were moving. They are really slightly used. Since they were up for 4 days. I didn't even screw anything, the base moves all over allowing me to simply stand and point where I wanted. They work great, pic quality is better than I expected. They have a manufacturers warraranty of a year and would cover for another 9 months at least. I have original receipt. If you purchase all 3 cameras together the price would be $147 plus combined shipping of $10. So $157 for all 3. You save over 70 bucks.
