Did the right thing to resolve my issue.
Covered my cost with little hassle. Started down the path of going back to manufacturing company but decided to just do a refund. The product was a floor vac that died.

Quick, Simple, and Stand Behind what they sell.
Filed a claim and immediately received a response with instructions. Once I mailed the defective product, with the provided mailing label, I received my refund. Quick, simple, and honest.
