I purchased my item six months ago but I just opened the box and discovered that the unit is not working, is it still covered under warranty?

The warranty period begins immediately after the date of purchase, check your manual, if your unit is covered for 1 year (365 days) then please contact support@curtiscs.com to begin the warranty process. If your unit is covered for 90 days, unfortunately the warranty period has expired. We strongly encourage everyone to test all units immediately when you bring them home to avoid disappointment.
