I own two 1UP racks - one for me that I've had a while, and one for my wife we bought more recently after she bought an ebike. The company's customer service has been fantastic at quickly answering any question I had, and they're great for having parts available if you need something.
Nice thing with 1UP racks is the flexibility with their AddOns. Do you mostly carry one bike and sometimes need to carry two? Buy a Single and an AddOn. Always carry two and sometimes three? Buy a Double and an AddOn. Attaching the AddOn takes a half a minute.
I also like that the racks fold up - the two sides fold forward - makes for a size you can stow in a car truck easily.
Be aware - unlike others it seems 1UP doesn't reuse the same ten lock cylinders, so while every lock in one order will be keyed the same, they can't match a new lock to a previous purchase. Think about the locking you'll need to do - the pin locks are nice - and buy all the locks at the same time.
