## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Not too bad to install, getting the spring onto the mesh before installing was the hardest part.
  

*by K***Y on Reviewed in the United States 🇺🇸 on May 8, 2022*

Was difficult to get the spring on the inside of the mesh dome, then the rest was relatively easy.

### ⭐⭐⭐⭐⭐ 







  
  
    Definitely a good investment!
  

*by K***. on Reviewed in the United States 🇺🇸 on June 2, 2016*

Fit perfectly for the exhaust of the furnace on my 2016 Kodiak Ultra-lite. Will definitely keep and insects from making a nest inside the furnace, and potentially destroying any of the working parts. With that said, the screen is a little pricey, but will definitely save you money in the future with repairs because of insects. It's a good investment. It took about one minute to install. They include the tool you need to attach the spring which holds it in place. Seems sturdy, and well made. I really only needed one screen.... Only one furnace, as with most campers. But, definitely saving the other screen if I need it in the future. Also, save the tool! They only give you one tool.

    Keystone Bullet RV use
  

*by E***N on Reviewed in the United States 🇺🇸 on May 15, 2014*

I liked the outside furnace screens that I ordered primarily because it was a recommended as a easy preventative measure for keeping insects/rodents from gaining access into the RV. The Cost was reasonable compared to in the event an animal or insect were to damage the furnace. The installation was an easy 30 second install, and the material the item was made of is solid and does not give the appearance of inferior material structure. It’s solid. I would recommend this to any RV owner as the costs as well as the install were the easiest thing I have done to our RV.
