I had a LeafFilter rep here today, he gave me a thorough demonstration of the system and several competing systems. He didn't know I already had 3 quotes from competitors.
Prior to his arrival I had read these reviews so I expected the worst. However, I was pleasantly surprised when the demo pointed out good and bad aspects of all the competitors. I was also surprised when his estimate was in the middle, not the most expensive nor the cheapest. He went on to explain that I could qualify for additional discount if I was flexible on installation time.
He was courteous, knowledgeable, and considerate of my time. After weighing all the options I opted to go with them at a price of $4200.
No when it's all said and done while no technology may be perfect there's seemed like the best option.
One poor review mentioned pollen clogging their system and that was the reason for the satisfaction, I spoke to two different leaffilter customers and they never mentioned that as a problem.
I will update this post after installation to let everyone know what I think.
