Product review (1 stars): Dundas Jafine MFX48D2DZW Semi-Rigid Dryer to Duct Connector Kit, 4-Inches
Buyers beware.  The dryer venting tube was torn in 3 separate pieces upon arrival and therefore cut my finger on this product.
Didn't expect a semi-rigid dryer venting tube to tear apart at the seams.  My thinner flexible ones never did that. Will be returning product
