Flame King Propane Tank Gauge Level Indicator, Leak Detector Gas Pressure Meter, Color Coded & Glows in The Dark, Universal for All Cylinders, Solid Brass (2-Pack)

Worked perfectly. Extremely happy!

Have always wanted something like this because it is so hard to determine gas level by touch or weight. Not very expensive. Quality materials. I recommend getting two so you’ll know how much your backup bottle has in it.

... good deal @ 2 for the price of what most charge for one. One for the RV & one for the Barbie;-)

Works well, would recommend!!

Good fittings and gauge. Much better than the stupid weight gauge.

They seem to be great, I’ve just installed them.Looks like no more guessing at the propane level

I love these for my propane. It tells me how much I have in there and I really like that without having to guess.

Shows the tank is full when it's almost empty. Can't rely on it, however it can be a good indicator if you are tracking when you are using the tank. Build quality seems good. Use them on my rv and they fit under the tank covers so that's a plus.

We use these on the propane tanks for our trailer. They are awesome to have when you aren't at a powered site. So far seem very accurate.

Nice fit easy install wish i had one before i ran out of propane .

So far so good

Vraiment agréable de connaître le niveau du propane dès que l’on allume le BBQ. Nous permet de prévoir le changement de bonbonne. Très satisfaite

Easy to install. Work great!
