Title: not good enough
Review: I've had 2 of these and neither lasted more than 2 seasons. Both leaked and tripped the GFCI. I would consider them again for about $8-$10 but not $28-$35. While they were working they kept a hole of about 8"-12" open all winter. This was sufficient to keep the fish alive. I'll need to find something either cheaper with a decent warranty, or more expensive with a proven track record.
Is the review positive or negative?
