Product review (5 stars): Much more sturdy than the flexible ones
I got tThis to side vent our new Samsung front loading dryer. The installation was a pain, but that was due to Samsung's venting design, not due to this product's shortfalls. The vents are much more sturdy than the flexible ones, which ended up getting holes in them when they bent. So far, happy with these ones because they are flexible enough to curve, but strong enough not to get broken easily.
