While the product Presto offers may be good (time will tell), the installation by Presto left a lot to be desired.
1. The gutter guards were installed with gaps at the seams. Presto did come out and "fix up" this issue.
2. One downspout was not connected to the drainage tile. I completed this connection myself.
3. LOTS of scraps and screws were left in my yard after installation. I picked up a pile of junk. When Presto came out to address No. 1, they picked up some more. However, I still picked up more junk later.
4. After the first rain shower today, the gutter was leaking at a joint. This drips right onto my front step. This would turn to ice in the winter. Presto says they will fix this in a couple days.
Overall, I was very disappointed in the installation. I had really expected better from Presto.
