Didn't last. Stopped working after 6 months. Really disappointed. I would think it would last at least 1 year.

I got this to add to a filtosmart 100. Keep in mind you will need an additional adapter kit for this. Working well.

Have it installed in the 100 canister. Had to crank it to full blast, but still 16 gal tank temp is 74ish. Wrapped canister in insulation blanket, and 1/2 the tubing. Still at full blast it's only heating max 74ish. Wonder is anyone else has experienced this problem?

Bought 2nd hand canister cheap ($40) and decided to buy a new heater for it. Fit perfectly. Don't know if it's working properly cause I don't have a thermometer.. but I'm not complaining for the price!

Worked well for a little over a year (Jan 2019 original purchase). Been broken for months now with a loud clicking noise and unable to heat 10g tank to 22 deg Celsius. Now here I am buying another since i have the Oase filtosmart thermo 100 Canister.
