How long does it last? (Ceramic Cartridge Heater)

Just wanted to pop in and say hello. I just got my printer about a week and a half ago and man oh man I have been printing like a crazy person

I have a Zonestar Prusa i3 and it's been wonderful. Right up till it wasn't

Today I was in the middle of a 10 hour print and about 1/2 through it stopped feeding filament. Come to find out the Ceramic Cartridge Heater died on it. Which of course happened to happen on a holiday. Anyway I ordered 10 more off Amazon and they will be here Wednesday. But.

My question is how long do these things typically last?

This one only seems to have lasted 165 hours so at this rate 10 of them will only last me about 68 days [printing days]

You might want to get more heat blocks and thermistors too, because the screws might be really tight after several hours of cooling and heating.
Maybe even tubes and nozzles and just change the whole assembly at once.

Then you might want to make connectors for thermistor and heat cartridge near the hot end, so you don't have to run wires all the way to the electronics every time..

Roger that. Already made plug in connectors for both the sensor and the heater cartridge down by the extruder.

How long do your heater cartridges normally last?

make sure it is rated for voltage you are feeding it or get higher wattage
