The product is great. Was delivered on time. But it came damaged due to poor packaging. I had to bang it with a hammer to straighten it out - I didn't have time to have a new one sent as this piece was holding up the installation of the siding on the house. So, I made it work, but it would have been nice if it was better packaged.
Horrible packaging, came in damaged, had my metal man at roofing contractor fix.
Sturdy solid copper vent. Will likely last as long as my house will. Quality control issues though: There are blobs of solder that were spilled on the vent and not cleaned off. Sloppy workmanship for a $260 product. Also, the vent was shipped in a GIANT box with lots of filler - This is a needless waste of resources. Couls be shipped in a much smaller box with minimal extra packaging.
Good: High-quality, beefy, last-forever vent. Issues: Quality control went awry, there are blobs of spilled solder on the back of the vent. Would have been very easy to avoid splashing solder on the vent, or remove it before shipping the vent. The vent came in a ridiculously gigantic box with way too much packaging. It would be slick to ship the vent in a box appropriate to its size.
Great quality and good customer service, but you will pay for it.
