This is a neat little multi-tool. It is made of metal so is heavier than it looks. And one nice thing is that none of the various tools are particularly sharp, unlike some other multi-tools I've seen, which means it shouldn't wear through my pocket too quickly!It has all the tools it claims to, around its circumference. The "bottle opener" is a bit of a gimmick because it is basically using the spanner/wrench slot, but it seems to work. The variable spanner slots will be useful for various tasks, and the gas meter cupboard triangular key is a nice addition.One thing worth noting is that the tool overall is quite a bit longer than a normal radiator bleed tool – it is 6cm long – so for this purpose specifically, if your radiator is very close to the wall or if you have a double radiator and the bleed valve is between two panels that are too closely spaced, there's a chance the tool won't fit in the gap, though it's been OK for all of the various radiators I've used it on so far. I have seen radiators in the past that are in quite a confined area, and this tool might prove too long for them. It's odd, too, because they put the radiator bleed valve tool on the end and the gas cupboard one in the middle. If they had swapped these around there would be more space for the bleed tool, and you'd also have more leverage for seized-up radiator bleed valves, and gas cupboard latches tend to be much more accessible and need less leverage too.You can remove the carabiner if you want to attach this tool directly to your key ring.
