As a ranger, the more people that use these things, the better it is for everybody.
It is only good, having less human excrement spread around a nice camping spot.
Also, had a cheapy from bigW, done about 15000 kms around the country and had a work out, I reckon it started leaking as well, only used for 1s until last weekend when it become a bit more used than expected, to the point of justifying a better one for an upcoming trip,
Got a dometic 10 litre from anaconda for $100 yesterday.
