Great deflector

We needed a way to divert airflow from a wall vent that blew straight onto my 92 year old Mom's shoulders -- this deflector was actually big enough for the size of the vent and we just pulled off the magnets and used some Velcro to secure it to divert UP rather than down. Lightweight but sturdy.
