Thin garbage
First this is 19” wide not 22”..im using this on a blower/vent and the vent tubing split so many times i went thru 140 feet work of this junk and i only had a 25 ft run!

Quality and price
Good quality and with Prime, good price. Other companies have comparable price but with shipping due to its weight, it’ll end up almost twice the price. I usually use a flex duct but sometimes you need something more bendable and easy to use. This fit the bill
