Very poor quality. Seams WILL separate if you don't plan ahead.

First off, if you are set on using these downspouts here is what you need to know. They are thin and flimsy. The seams will separate when you cut them. I don't see any way around it, so you must prepare for it. It will simply take twice as long as it should to do the job, but if you have more time than money, it can be done. Get some 3/8" sheet metal screws and screw the joints together at both ends and about 1" on each side of where you are going to make a cut. You have been warned. If you don't do this, you might as well plan to throw the whole piece away because the seams will not go back together. I tried cutting with a oscillating tool with a metal blade and with a hacksaw. No luck, both just popped the seams apart. My best luck was by hand with a pair of aviation snips, but still had to screw the seam together on both sides of the cut to keep them from separating. I'm not sure how these are rated as high as they are. Maybe if you never had to cut them, but I don't see that being very common. Can't speak to how long the paint will last or how they will stand up to hail because I just installed them, but they look OK for now.
