Question: How many snakes will crawl in the window if I don't use the rubber gasket?
Document: The rubber "gasket" supplied with this product is neither long enough nor flexible enough to follow the natural slope of ANY window. Thus my reason for sending the fan back for a refund (less than $10 for shipping I will have to eat) because Amazon gave me "Sorry, it's not our fault this didn't fit" which is total bull.Sadly, the fan seems quite robust and in full sunlight it kicks out some serious "wind" from the two small fans.The instructions on a piece of paper that come in the box are written in Chinese, but the box also has instructions and drawings inside the lid that easily explain how to install and use the fan, but the fan can not probably be used on anything other than a vehicle that has square or perfectly rectangular windows.
Nothing is like being hot, being stuck in a car, and can&#8217;t get out. Well, unless you want to get hit by cars. Not a good option. This is how I spent most of my summer. Until I discovered Kulcar Solar Powered Car Ventilator. I know longer have to worry about being so hot and my car doesn&#8217;t have to work as hard. The best part about the Kulcar it&#8217;s SUPER easy to use. Slid it on your window and tighten it up.
I wanted to add a photo showing the natural curve of my driver's side window and how their material can not accommodate the curve, but it looks like Amazon now longer allows for videos and pictures... But, the person who wrote the review about his Prius and the difficulty with the rubber strip, I think you can get the idea that the rubber strip is just a bad way to try and seal off the window along the juncture of the window channel (frame) and the glass itself.
I am disappointed. The unit does not generate cold air and minimal cool air. It seems to have very little impact in a tropical location like Hawaii. It is noisy and has no on/off switch, so one must be subjected to the whirring sound of the fan unless it turns off, on its own for no apparent reason. Then it turns itself on again. Also it loosely fits on the window to the extent that it rattles against the window glass when on a bumpy road. I would like to return it but I have already cut the black rubber strip.
The manufacturer suggests taking it out of your window when driving. So you have to set it up each time you get out which is not all that quick and I'd say a major deal breaker for many.My suggestions:1. Find a solution to the slope in people's windows, something easy to attach.2. Perhaps add a battery for the inevitable shade.3. Definitely add an on/off button.
Ok, now here is what I think this Kulcar car cooler works just like it was designed to do, very easy to install position the solar panel facing directly at the sun to get the best results. Comes with everything you need to install it in the window of your car with the rubber strips, here is one thing I found that didn't benefit my car as much as it would a smaller car being the space is a lot larger in a big car, I believe I would need more than one to be effective to cooling off the whole car before getting into it, but if I had a two seater car I am sure it would cool it down a lot, It just so happens my car sits 6 seats.
We have three vehicles and in order for this fan to be placed in the window of any vehicle, you must cut a rubber liner supplied with the fan and slide the rubber liner along the top portion of your car, van or pickup glass window. The fan is supposed to butt-up against the rubber, then your window is rolled up so that the rubber liner can slide into the window channel (typically felt or rubber itself) and the problem is, that no car window is squared off or straight. Most windows have a gentle curve as they slope down from near the roof line to where your rear view mirrors are located on the bottom part of the window on the outside of your car, van or pickup.One previous reviewer stated this fan didn't work on his car and I can see why now.
Does not install well on 2004-2009 Toyota Prius. Stripping too short for front windows and must be cut and pieced together for rear window installation, as there is a 1&#34; gap between the window and rear of the frame when item is in place Flops around and is difficult to position when rolling window up. Too many gaps around item, using supplied stripping. May have a different experience with a different vehicle.Great idea. Did keep the car somewhat cooler, just not good for my vehicles.
I bought this because I live in the south and I thought this would keep my car cool. I was very wrong. I saw four major problems:1. The gasket doesn't fit most windows that slope.2. The device has to be in direct sunlight at all times. If there's even a slight amount of shade on it and it's nothing but heat for you.3. The fan, although it sounded powerful, never kept my car cool enough. Which may have been because of problem number 1.4.
Kulcar is a very nifty concept and something that parents in particular will want to have installed in their cars this summer. I love environmentally friendly products, and I have to say I&#8217;m impressed. The idea is this: it&#8217;s essentially two fans within one mechanism that cool down your car when it&#8217;s parked in the sun. What I like about it is that it&#8217;s solar powered (! ), meaning you use less gas blasting the air conditioning to get the car to a comfortable temperature.
Answer: If you can refrain from overfeeding your car's mongoose, the snakes won't pose a problem.
