Price is right, extremely right.
Hard to judge quality but time will show, looks good and I see no obvious faults/flaws.
One drawback is the short cord, 20 meters, since maximum height is said to be108 meters which is quite deep, so a longer cord, or at least some hint of how to prolong it while still achieving IP68 would be nice.
"This well pump has a built-in check valve to prevent back-flow (an additional check valve is highly recommended)"
Don't be fooled, this pump comes with absolutely no valve at all, the moment it turns off everything backflows.
Extremely easy to connect, R25 thread and that's it.
I really recommend this pump!
