Good safety shut-off feature, but this could be complemented with alert.
4/5
The dryer could do with a "clear lint filter" alert. The first load, which was new towels (hence the big lint despoit), ended without drying. I presume that was because the lint filter had filled up and the machine ended the programme as a safety measure. That's a good feature, but adding a corresponding alert (perhaps both visible and audible) would be useful, to prompt filter clearing and programme resumption and thus save the user's time.
