VAYINATO® Manual Fish Tank Water Changer Aquarium Dropper, 50Ml Aquarium Clean Pipette Dropper, Fish Tank Cleaning Waste Remover, Aquarium Gravel Cleaning Straw Aquarium Tool by Petzlifeworld

I've used it for my small ponds and it's been quite useful, suction power is not strong but good enough. Pros : >Can get into narrow spaces >Sucks out a lot of debris,very effective at cleaning >Less water wastage >Convenient to use Cons : >Since the tip is small,sometimes algae and small snails get stuck and block the dropper,you have to open and clean it when that happens. >Time consuming Bought for Rs.266 but now price has increased.

The product is of good quality and the suction is enough and there's no leakage of air. It's easy to handle although the size is big enough.

Prefect product

Very useful product. I feel like the price is bit high for the quality.

Worst product I have ever bought on Amazon. It had cracks, drips liquids & has no suction power

It is good quality plastic and works well as a pipette. At present, it is an incomplete, though workable, solution to clean fish poo in a low tank, but requires repetitive working.

Value for money, easy to use, durable and suction power is also good except there will little leakage if you suck too much water but manageable.

Works well. The fluid won't reach the rubber, so the rubber will not fail as quickly. Nice design
