I've only used mine for one season so far, all seem to be holding up fine so far. I bought 3 dif brands off amazon, just following price vs reviews and some comments in this sub (Jeria, Vivosun, Opulent systems). No major differentiator yet.
As for the volume, I made a similar post, in short, I think "5 gallon bucket" might be actually more than 5 gallons (please double check the measurements/math).
