GasPods AeroHance Save Fuel by Making Vehicles More AeroDynamic Attach Magnetically to Car Roof - Kit of 9

Shipping was super fast. The magnet sticks to the car perfectly. I used a tic-tac box to separate them evenly on the top of my trunk above the rear window!!! I've had them on the car for several days. I've had people checking them out in the parking lot & people passing me on the highway looking at them wondering what they were. They are definitely eye catchers too!!! I would definitely recommend these to anyone.

This is worth the investment. It cost 50 bucks but I am saving hundreds!

I really like how they look, however I decided to tape them down with 3mm auto tape due to the fact that by being magnetic, caused too many problems with them coming off.

Not sure if the mileage improved however I do like it on the roof of the car.

These pods really do work and save gas! Just bought a 16 yr old honda element some months ago with a crappier mpg rating than my other two because of the weight of an all wheel drive. But happily a friend bought these for me on Amazon and i consistently get better mileage than the two front wheelers I've owned so I'm a happy camper. I seriously thought I'd take a hit in the shorts with this AWD, but the gaspods have proved me mistaken!

If you don't know anything about aerodynamics, these work, but only at highway speeds. If you're only in stop and go traffic, you will not see any benefit. On the highway, however, they actually do a good job.

Adding the GasPods to my Prius bumped my MPG 10% for the last 20K miles while mainly driving at highway speeds....they work!Adding them to two other vehicles next.

Do Gas Pods provide any assistance in placing these pods on the rear roof line or truck area??
