What is the difference between the standard version and the "outdoor" version ?Not brand new, it's OPEN BOX! Open Box items are products that have damaged packaging or are otherwise not suitable to be sold as new. All items are tested to be working by a member of our team. Open Box items come with a 6-month warranty instead of the standard 1-year warranty, and are not eligible for any warranty extension offered to new products. We will not accept returns of Open Box items due to cosmetic damage or other non-performance-related issues. All sales of Open Box items are final and not eligible for a return or refund. If for some reason the item is defective on arrival, please contact [email protected] so we can arrange a replacement.
