The dual-hose kit arrived quickly and included everything needed to convert my Dreo AC516S, including the replacement rear intake plate. Installation was straightforward, and the system is working correctly. My only issue is that for my vertical sliding window, even the shortest supplied extension panel is too long and would need to be cut manually, so I am temporarily sealing the remaining opening with tape. More size flexibility for shorter window openings would improve the kit. Overall, it is a well-made and useful accessory.
