Review on 🔧 Builder's Best 84049 SAF-T-Duct Zero Dryer Vent Periscope, Adjustable Length 0-5 inches, 4" Diameter x 8 feet, Aluminum by Jay Buford

Other reviews were correct. The product is not of good quality. The metal is very thin. This block has two ports. One to install on the dryer air outlet and the other to install on the dryer outlet. The problem is that the two fittings on the unit are the same size as the dryer vent pipe and the dryer outlet pipes (4 inches). Even the "crimped" connector isn't crimped enough to fit snugly into the dryer opening in my wall. I had to make 1" cuts in both fittings to fit it over the dryer outlet and insert it into the dryer vent. Then I used a large amount of metal tape to seal the places where air was exiting the dryer. I got it managed to do it but it took a lot of time and nerves all the manufacturer had to do was crimp another connector and make the connector that connects to the dryer outlet a bit larger then I wouldn't have any problems. Not recommended.
