Hydor 61300 Impeller Koralia Evolution Review

We purchased this accessory for our aquarium from the Pet Supplies category with high expectations, but it turned out to be a complete disappointment. Based on our own experience, the impeller did not perform how it was advertised and slowed down with time. The only positive aspect was the easy installation process. However, the consistent underperformance resulted in a negative impact on our fish and aquatic pets. Overall, we would not recommend this product to other aquarium owners.

That shows, the only thing wrong with it is the missing washer between the body and the bracket. and the kit is not disassembled but works very well

That's what it says, the only problem with this is that there's no washer between the body and the bracket and the kit won't fall apart , but works very well
