Review: November 27, 2018
The salesman was very personable. He explained everything very well. He didn't try to hard sell. He gave pros and cons and explained the incentives he could give us. I was very happy with his presentation.

Review: October 9, 2018Completion: October 9, 2018
I feel you should have had a sample to leave with the customer to do his own testing & comparing. He should have provided me with a written estimate, rather than marking the amount on the brochure. I would have liked a written proposal.
