Perfect for the intended purpose.
by Joel from Los Angeles CA USA 
Pros: Good size, does what it should.
Cons: None
Review: This jar is a perfect replacement for the "shot glass" sump tester included with the aircraft. It allows one to test all of the taps on a 172, and then dump the fuel back into the tank through the strainer--rather than just dumping it on the ground.

this is great
by Jim from Claremore OK USA 
Pros: no waste
Cons: none
Review: No more fuel on the ground. I have 12 sumps on my '99 C182. This allows me to take samples from each and pour them back into the tanks. Really nice!

Exactly What I Wanted
by Dave from Owasso OK USA 
Pros: Simple, reliable
Cons: None
Review: My instructor has one just like this. We tested his to see that water in the fuel would in fact be stopped at the filter when you empty the container.

A great product.
by A Customer from NJ USA 
Pros: It is a nice fuel strainer, fits both kinds of sumps, and the fuel can be returned to the tanks if clean.
Cons: The reversible sump addapter can be hard to switch, but comes out with a little work
Review: This is a nice product. It can take a lot of fuel so you don't have to worry about getting a sump of only water and not realizing it isn't blue. Also, you can return the fuel to the tank without worrying about sediment, finding a waste fuel container, or throwing it on the ground.

Great product - everyone should use one
by Keith from Hartly DE USA 
Pros: Takes large sample, Good view of fuel quality, Return gas to tank
Cons: Larger to store, You see how much crud is really in your fuel system
Review: This is my second Gatts jar, replacing one I lost somewhere. The 12 oz jar is more sturdy than the 16 oz version. I like being able to put the gas back in my tanks - it really does a good job of filtering out trash, although I never have water in the gas to test that feature. I also like being able to drain more gas out, to see what was in the lines and gascolator. The standard 2 or 3 oz cup isn't enough to get a good measure of the quality of the fuel

So far so good
by John Countryman from Petaluma, CA 
Pros: Saves fuel, saves money, saves the planet. Easier to see AVGAS color.
Cons: Seal leaks. Takes some practice to drain sumps without spilling.
Review: Have only used it once so far. Large capacity makes it easier to see contaminants and color of AVGAS. It does leak a great deal around seal when pouring back, as others have commented. Will try petroleum jelly and see if that helps.

Should be mandatory to use
by Andrew from Pittsburgh PA 
Pros: Better for the environment and gives you a much better look at the
Cons: Slightly cumbersome to put in a flight bag, a bit pricey for what it is
Review: I know in many locations, sumping fuel and dumping on the ramp is illegal. Yet at my airport, the practice is permitted. Since I lost my regular fuel strainer, I thought I'd buy a GATS jar. I've always felt bad about dumping fuel on the ramp and trying to be a bit more responsible about our environment is one way we as pilots can keep the anti-airplane people away a bit longer.

I like the GATS Jar, easy to use and easy to change from the "push to sump" type valve to the petcock type valve found on some airplanes (I am a CFI). And now I can re-use the fuel I sump (as long as it is safe) instead of wasting it on the ground. Plus, you get a much better look at the fuel and the possible contaminents in your fuel system.
