Product review (3 stars): ... rigid vent tubing which is not that flexible but recommended for our new LG dryer
The 90 degree vent elbow did exactly what it was designed to do and definitely saved rear wall space especially since we were using the semi rigid vent tubing which is not that flexible but recommended for our new LG dryer. We paid three times the cost since I needed in a hurry for the same basic elbow so if you have time shop around and that was the only reason for the lower rating. Its basic sheet metal but does the job.
