Great for the price, but not high-end by any means Review by Ken
This is a very basic powerhead. it is great for the price, but if you use it with timers, you may find it a bit noisy on startup. You get over it real quick. I appreciated the low cost as I got into this hobby, but I have since replaced these pumps in my tank with DC controlled ones. With even my short lifespan of usage with these, they were worth every cent and I have since started using one in my water change container when I am mixing up a big container of water.
