Will not last as advertised! Agent seeps out beyond serviceable limits around the bottle and discharge head after a few years.

After 4 years in my aircraft this expensive fire extinguisher has bled out empty. So much for a 12 year shelf life!! Contacted H3R for warranty service and they tell me this unit is manufactured in Canada and they will not stand behind it. Multiple leak out complaints and two that exploded in R44 helicopters. The FAA is aware but for whatever reason, Spruce continues to sell these. Dont do it!! Expensive lesson learned.

My RT A400 completely leaked out inside of three years after purchase. I was provided a new one at no charge, but it also leaked out within 3 years. There is a service bulletin issued against these. Recommend buying an all metal extinguisher with a gauge.

At 3 yrs, 9mos, we discovered it was totally empty. Never used. Seems to drain on its own over time. It was OK during our annual 9 months ago.

Both of the ones I have are empty and did not make it close to the advertised 20 year shelf life . No gauge, non-refillable. I will not buy again.

Saved my plane from burning to the ground when battery wires contacted each other and caught fire. Well worth the money!

Leaked to below usable weight in three years.

Small and compact. Last on average for 8 years before it falls below the recommended weight of 500 grams. Never had one just discharge on its own.

Leaked out after 2 years

I had this model for some time mounted in between the seats of my RV6. Well, I finally really needed it! I was burning in new brake linings when a fire broke out in my right main gear. The little RT-400 did a great job putting out the fire.

My RT A400 is holding up as advertised...I bought it in 2012 and after 7 years, it still weighs the same original 1.2 lbs. and no signs of leaks.

Nice a little pricey but its perfect size for the plane

Shipped promptly and received in excellent condition. I fit-checked the unit to my airplane and its just as expected. Will install soon. I also read the instructions and will weigh the core unit annually to make sure its fully charged. Very good product for small airplanes from the limited experience I have with it. Lets hope I never have to use it.

Less than 50 hours of flight tome and the bottle self emptied, with no visible damage or marking. Weighing before every flight is simply impractical. Would not recommend this unit

It is small and lightweight, so fits well in my small experimental aircraft (Sonex). But mine has not lasted the advertised 12 year shelf life. Mine is about 6 years old and weighs less than 200 grams, meaning it has leaked all its contents. Ill probably purchase another, but not happy about the short life of this expensive extinguisher
