I really like how simple it is to use! It's easy for people who aren't tech-savvy at all.
There are lots of options in terms of customization, but I wish there were more customizable templates available so that we could get even more out of this platform without needing someone with coding knowledge to help us set up our system. We used the thing system because my husband was having trouble keeping track of his stuff (and he has an entire closet full!). This solved both problems by allowing him to keep everything organized AND giving me access to all of his items when needed.
