It worked a charm - nice and sturdy
Bought this for my tiny Italian percolator. It worked a charm - nice and sturdy. The outer circumference means it can sit astride a lot of large hobs but the spokes come in far enough that you can use it with small items. There are four grooves on the underside to slot it on the hob so that it will not slide around during use. When it's cool, I also use it as a trivet.

Great for small milk pan / kettle. Better quality than other "equivalents".
Sits nicely on the hob. Good quality enamel seens durable - unlike the more expensive & identical looking equivalent that I purchased previously.

Turned my gas hob into an Aga (without the mortgage)!
I’ve tried the cheap flame diffusers — they warp, they stink, they burn food. This one? Solid cast iron, enamelled, weighty in the hand, and it actually does the job. No hot spots, no buckling, just lovely even heat. This little enamelled slab of Italian genius turned my gas hob from a temperamental dragon into a calm Aga-like hearth. No more scorched pans, no more swearing at my poor hubby for destroying yet another invaluable Le Creuset. It’s heavy for its size (you could probably defend yourself with it if dinner goes badly), has proper notches so it doesn’t wobble about like a drunk flamingo, and a handle that saves you from playing “Guess how hot this is” with your fingertips. Does it make my food taste better? Maybe... Does it make me feel like a domestic goddess with superior cookware taste? Absolutely. Frankly, if this diffuser had a dating profile, I’d swipe right - and probably be better off 😂

Great heat diffuser for a gas hob
The wire handle is detachable and works well to move the diffuser when hot. I use this when I need a lower, even heat for a simmer or when making a sauce without a bain marie. I also use this for cooking with my ceramic tagine on the gas stove top. No issues with the item distorting. The enamel finish seems robust.

Absolutely perfect for moka pots, solid and fits nice and flat on the hob.

Good quality gas ring reducer
Heavy (for its size) cast iron reducer made in Italy. The finish is black and a fine grain coarse structure which matches the cast iron frame of the pan supports on my gas hob. It is not enamelled as some people have written and on my item the surface has not degraded after being in a fairly fierce gas flame for more than an hour. The underside has 12 locating lugs and on my hob can move but it will not fall off the existing pan support frame. Also it’s heavy enough for gravity to hold it in place when placing a pan on top. I have now had in daily use for three months and my rating is still 5 star. It still looks as good as when delivered - the surface is not degrading. A pro or a con depending on your point of view - on a gas hob this ring reducer heats up and being a resonably heavy (for its small size) lump of metal it retains the heat when the gas is switched off so that the contents of a pan will continue to cook for a few extra minutes. If you drain a small pan of cooking water and then immediately place the pan back on the top of the reducer the bottom of the pan will get hotter and perhaps burn the bottom layer of what is still in it.

It's worth the extra cost ..and works perfectly
This cast iron hob reducer works perfectly and provides a good, stable base for small pans. It is not sprayed with some nastily smelling 'finish' to make it look good so there are no fumes or smell when you use it - even for the first time. It seems to fit various sizes of smaller gas hob burners. Just make sure it sits centrally because it is not designed to be a tight or snug fit and is ideal for the smaller burners e.g. used for coffee percolating; preventing smaller pots and pans from tipping over - see the pictures. It's a bit pricey compared to others available but is far superior so worth the extra.

Perfect trivet for my mocha pot
I got this trivet because my 3 cup mocha pot couldn’t sit stably on my gas stove top. This was a great fix. The trivet looks really nice on my cast iron stove top. It fits perfectly and really does the job that I got it for. Great buy, high quality and I’d highly recommend this item.
