Product review (3 stars): Good enough for most people.
Good enough for the time being. If we stick with the washer that came with the house, I'll make my own clean/dirty sign eventually. Until then, this seems about as good as it gets.

Pros:
- No need for magnetic dishwasher. Works on wood, stainless, etc.
- Saves time. So glad I don't have to open the dishwasher every day to inspect for clean/dirty. It seems like a small thing, but it adds up.

Cons:
- screw install option not available, only sticker
- somewhat overwrought, yet seems almost flimsy
- not particularly readable (compared to available magnetic options)
