The 3-year warranty always applies, regardless of where you purchased the product. All warranty replacements and repairs are handled directly by us. There is no need to contact the distributor where you purchased it. Also, you don't need the original receipt. As long as you have the unit, we can repair or replace it under warranty. Also, if you can't remember when you purchased the unit or if the 3-year window has already closed, please contact us anyway in case we can help.
