The pump was easy to install, it works just like it should, and it was delivered rapidly. The price was not out of line compared to other options, but everything is overpriced these days.

it's just perfect for a small little tank. read some stories about pumps killing fish that get trapped on intake holes but my fish has been just fine for about a month now. the intake suction is small and on bottom as well.
