Used it today, first time. Actually prefer it to the shurflo!
Because of its shape, and handle, so much easier to manage than s-flo. Absolutely no need to mount on a trolley, even when full.
Switch is on the side at bottom, but this is still better than directly underneath.
Also, can't really say that smaller capacity (15L as opposed to 18) proved to be an issue.
Downside? Definitely a weaker flow, .. but still good enough I think.
If it lasts a year, I'll be more than happy!
