Review on PERSUPER Aquarium Output Aerator Valves by Crystal Cornwell

I bought a Revain air pump a few weeks ago. It was nonsense. I bought it to hatch Artemia eggs. The noise level is low and doesn't bother me at all. I hatch Artemia in the kitchen, so the noise level is important. The pump is quite powerful and dispenses the two 3 liter bottles I have with ample water circulation. Continued May 11, 2021 - still works like a charm, 8 months of continuous use and no issues. Today I wanted to buy another one to use with multiple outdoor kegs. The current price is shocking. I remember buying it for $11.99 and now it costs almost three times as much. I went with another brand, also with 4 outlets, for $19.99 and am only giving 3 stars due to the price increase.
