Dickie Dyer Heavy Duty Immersion Heater Spanner 86mm is rated 3.1 out of 5 by 14.
Rated 1 out of 5 by from Wrong size for immersion heaters !!! The product is made from spheroidal graphite iron, this makes it very tough and perfect for the job it is designed for. Unfortunately it is the wrong size for the immersion heater I bought. According to the listing in the catalog it is supposed to be 86mm but when measured it is well over 90mm. The one I was sold turned out to be second hand as the paint finish was damaged as if it had already been used-(I did not notice this until I got it home!). Added to this the original store I bought from (click and collect) phoned me to stop me collecting as "they had no stock" despite their system saying they had 2, I was promised that they would refund my payment, so far they have not, I cannot get in touch with Toolstation as no one answers their phones. This meant that I had to buy from a different store, I am now in the position that I have been charged twice for a second hand tool !!!!!!!!!!!!! I will be thinking twice before using Toolstation again.

Rated 5 out of 5 by from Just the job Bought a steel spanner, it didn't work, I just managed to bend the Tommy bar, used this, fitted it over the immersion(the fit could be slightly tighter) but it was okay, gave it a "clonk" with my lump hammer and the immersion loosened first time. Great tool. Highly recommend, having one in your tool box.

Rated 5 out of 5 by from Great tool Needed to change my Immersion heater. My original, pressed steel spanner couldn't move it. This heavy duty spanner had it out at in no time. Highly recommended.

Rated 4 out of 5 by from Heavy duty A stubborn element bent my old spanner of 15 yrs - showed it this one and it loosened itself in fear. I agree it is a bit of a loose fit but I assume this is to cover any manufacturer size discrepancies in the elements. As someone else said - when you are removing a difficult element - you are throwing it away so it does not matter. Ultra robust - can't see anyone breaking one of these in use.

Rated 5 out of 5 by from Your only chance for extracting an old immersion. A very positive fit in your immersion. My old One just rounded off the edges as it changed angles. This fits sniffly and the angle doesn’t change. So if you are trying to take an old immersion out start with one of these. The ones with the sliding bars may help once it’s free if there’s not much space.

Rated 2 out of 5 by from Not good The design is fantastic for those stubborn immersion, nice and string. BUT it's too big to fit immersion. In fact it was that loose a fit I had to put a 2p coin to take enough slack out so it would grip.

Rated 1 out of 5 by from Wrong size 90mm instead of advertised 86mm Useless as does not fit standard 86mm immersion heater.

Rated 4 out of 5 by from heavy duty, heavy weight really heavy duty tool, i was really impressed when i collected it. however, it turned out to be too wide for the size of my immersion heater so i couldn't use it without it slipping. check the width before purchase!
