When I received the elevator the metal casing around the elevator was smashed and bent. The elevator looked to be okay. I noticed that the accessory box was open on one end and parts were coming out. If the motor bar wasn't in a plastic bag it would have been missing. As I inspected further I noticed that the tension gear for the chain was missing. At first, I thought it fell out of the open box of accessories but then I noticed there was one bolt left where the gear was supposed to be. Whoever stole the gear must have been in a hurry and left one bolt. I can't blame Titan as this probably happened in shipping but I would suggest that they secure the item better to prevent theft. Customer support was helpful and the missing parts are hopefully on the way. This problem has set me back by a couple of weeks and time is money. As for assembly it was easy to figure out and can be done by one person. Still waiting on parts...
