Note: Buyers bear the cost of shipping and handling cost round trip for warranty services. Warranty does not cover consumable accessories and parts such as bulbs.

Warranty service times vary throughout the year, and are processed in a first come, first serve manner, when parts are available and in stock. Most repairs/replacements are done within 1-2 weeks, however if there is a long line during the busy season, or if your parts need to be ordered from our manufacturer, processing times can be up to 6-8 weeks. We appreciate your patience and understand everyone has a critical need for their unit, and do everything we can to ensure that these requests are handled as quickly as possible.

Defective/Missing Items

For defective items or any missing items from your order, please contact us right away to let us know of the issue.

We allow a 30 day period (from the date of receipt of the item in the mail) to report such issues--any items missing after that time frame will need to be purchased, and any defective items will be treated as warranty issues for repair or replacement only (no returns for refund).

For missing items and broken items, we do require a picture of the shipping label on the box, and of the items that arrived with your unit for verification before we can send any missing items or replacements to you.

Return Procedure

To initiate an RMA, please send us a message through the store you purchased it from. Include your order number, reason for return, and if any pictures are required for your claim, please include them also.

From there, we will process within 24-72 hours, and if approved, issue you an RMA number and instructions on where to mail your unit back to. If qualifying for return shipping covered by us (for defective items within 30 days of receipt), your return label may take another 24-48 hours to process and be received in your email inbox.

Follow the issued instructions, and once received, we will process the item in, and check to ensure everything is there. We will contact you when the item is ready for return shipping (if a warranty request), or simply issue your refund with the appropriate deductions (if any) once processed.
