### ⭐⭐⭐⭐ Functional with flaws
*by T***R on July 21, 2025*

I wasn't sure if 3 or 4 stars was better so rounded up. Overall, the kit is doing what I needed it to do, but I definitely had to modify it more than I expected. I knew going in that the hose was gonna be two tenths of an inch bigger then I needed, but I knew I could make that work. And I did with a little bit of tape. What I didn't expect was for the part that goes in the window to be as flimsy as it is. On the plus side, it fit my window really easily, which was a relief. Because I've had problems with other kits in the past. But the screw, no matter how tight I turned, is not keeping the panels from sliding, if they are pushed. To be fair, I am hopeful this will not be a problem, but as you can see from the pictures, I did add a whole bunch of tape to help secure the window unit. I initially added the tape to keep the hose component in the panel as it was falling out, no matter what I did to lock it in. It looked like there were little screw holes on either side, but there were no screws to put in. And I didn't see anything to "clamp" the piece into the panel, as was mentioned in the instructions. So tape it was. There was sealing tape in the kit, but it was completely worthless for my needs, and so I made do with the tape I have. The other thing that surprised me was, although there wasn't a gap on the top of the panel, which was lovely, there was a gap between the bottom of the supplemental panel portion to the window frame. And so I needed to add something there to close up that gap. Especially since there was a definite wobble in the panel when I wa pushing on it during that process of checking it. Tape to the rescue! I bought this unit to stay-in the window because I already had one installed for the day time location of the a/c. That one is in the living room, and I wanted to be able to move the portable unit from room to room, but because I needed to tape it to the window in the living room to seal tge gaps, I needed a second window kit. It was that or by a second a/c. So overall, I'm happy so far. I will update if that changes.
