I guess they all make mistakes, but I much prefer UPS. I have had no problems at all with them. One box did come with a torn and mashed place in it, but the driver asked me to open it and check everything before he left. That way he could just take it back if anything was damaged. Fortunately the damage to the box never got through all the packing and the items were ok. But I did appreciate his asking me to open it right then and not just driving off and leaving me to find out if anything was damaged.
