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.

There is vacuum leakage from the suction bulb, i have a similar product this product is average doesn’t have proper suction , the dirt falls back to the tank, the rubber bulb is also pretty hard .

The bulb is not large enough to pull in any more than 40 ml even after crushing the bulb in my fist. Water drips from the tip without pressing the bulb. Durable. Good suction. Easy to use. Works well. Plastic tube clarity: 3/5 Rubber bulb: 5/5 This 50ml model definitely has a 30ml bulb on it. Very dissappointing. Update: releasing the bulb slowly let's you get all 50 ml in at once. Releasing it quickly let's air in from elsewhere, leading to a max capacity of 30ml.

Prefect product

Makes your cleaning very effective..the number of times I had to completely empty my tank to clean it drastically reduced

Does not work

I ordered and product was damaged because of bad packaging raised for replacement again the product was ok but suction was very less so I returned . Don’t buy it its not good product.

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.
