The unit shipped late and came delivered damaged. The order took 10 days to arrive. The boxes had no external damage, when opened the foam was crushed at top of the unit and the cover was broken where the screws attach to the unit, also the 4 plastic holders on the circuit board were all broken and circuit board was was damaged (the receiver unit had seperated from the board). I called and left a message with customer care on Saturday June 9, 2018. I would like a call from customer service, I will re-call on Monday during business hours to get replacement parts. Thank you Keith Royer. I can be reached at 617-283-2959
