Rated 3 out of 5Â by zzardy Too big.Can puncture cylinder.
I found this spanner slightly too big for the immersion heater nut and unless you're very careful it will drop completely over the nut and dig into the copper cylinder while turning it. Had to go back to my flat immersion spanner which easily undone the immersion and was far more controllable.

Rated 3 out of 5Â by Geordieman54 Stronger Bar Required
Box spanner fitted well however bar bent when tapped with hammer on a very tight element.
unfortunately unable to remove even when adding on extra leverage, the bar bending further didn't help

Although this is slightly more expensive than the flat ring spanner I would thoroughly recommend this. It feels like it will last a few generations. It undid my old immersion heater with ease. I managed to thread the mains lead through the socket and still undo it so no need to remove the cabling first - once unplugged!
This is twice the price for 10 times the quality.
