## Customer Reviews

### ⭐⭐⭐⭐⭐ Just what I was looking for
*by E***E on June 13, 2024*

Pro: Fit my window horizontally, and it worked beautifully once I figured out how to put the extension piece together. For my window, no cutting was required!Con: Putting it together seemed simple enough, but the instructions were lacking in some specificity. For example, in which direction the pieces should be applied. Also, I would have liked the exhaust hose cutout hole to be closer to the center. I only used one of the extensions and it's exhausting a smidge into my window panel.Nonetheless, none of the cons are a deal breaker, and I recommend that you get it!

### ⭐⭐⭐⭐⭐ Watch the How To Video. Great product for the price!
*by D***O on May 15, 2023*

I had read previous reviews and agree that the written instructions aren't great. I watched the instructional video provided on the products page here on Amazon. I took screen shots of all the nuances and it worked well. The mistake I made, is it was too long and I didn't consider measuring the length of the window before I ordered. But, we were able to cut it down to make it fit. Also, another tip for fitting the hose into this adaptor (I read reviews where it didn't fit) and here is what we did: we used a wire cutter and snapped the first wire on the hose so that it would collapse and we could then mold it to fit into the hole provided. We also used duct tape to seal both ends of the hose into the AC unit and this adaptor piece. Honestly, I cannot imagine one would ever fit perfectly without some sort of rigging (we used silver duct tape for the security but will cover it up with white tape for aesthetics. Its in our bedroom so its not like people will see it, but for those who keep it in a more public place in their home should consider this option). Also, keep in mind that the hose has some weight on it and this duct tape not only seals the hose into the adaptor and AC unit outlet, but it also helps to alleviate the downward pressure of the weight of the hose. Lastly, we didn't use the air seal yet so I don't know how well that will work. Overall, I think this is a very acceptable product for the price but know that the video makes it look simpler than it is and to embrace duct tape to perfect the functionality of it. (I think it was at least half the price of what I could buy it for at a local store like Home Depot).
