How do the Tunze clones, otcopus propeller pumps, compare?

[Nerdy Nudi]

Finally got in from the long weekend and saw the sale, hopefully Ill get my order done in time.

Noticed a new octopus propeller pump priced really well. But how does it perform compared to the Tunze 6045's? Are they much larger?

Thanks

Tunze's are top notch. The Octopus pumps are a decent alternative, but if you want longevity and access to replacement parts for quite some time, stick with the Tunze.
