To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
First let me say the company is amazing they have wonderful customer service. Second the pump is great I am using it in my vivarium for my waterfall. The pump has many great features you can choose how much water pressure you want, there are suction cups at the bottom to hold it in place. It doesnt get clogged, this pump is just what I was looking for. Lastly it is small so I am able to conceal it in the vivarium. I would recommend this product.
