I don’t ever leave reviews however after reading the only other review this item has after I got off the floor from laughing, it does fit a 240v 16amp socket if they are trying to plug it into a 110amp that might be because they have perched the wrong time, however this is the 2nd one I have bought no issues.
Didn't fit the 110 extension and when I managed to swap the heads, the power was very low.
