Cheap and cheerful, but beware.
For the price, this is a pretty decent piece of kit, so if you have a couple of rings you want to resize then this will do. A word of warning though, it will really only work well with softer gold/metals. Don't even think about trying to resize say a 9-carat gold ring as the metal is just too hard.

Why isn’t it round?
It’s a good quality kit for a decent price, but the actual ring taper is such a let down. I bought this to reshape a couple of rings that had lost their roundness, however the taper, for some ridiculous unknown reason has two deep, wide ridges cut out of it and running down its full length at each side. It’s not just fully circular and rounded the whole way around. Using it to try and shape a ring is a lot less convenient because of that. You have to use it intelligently and keep rotating your jewellery to avoid making a figure 8 shaped ring. It’s really frustrating, because it seems like it would be more work for them to create this product in this way, and whilst I’m not an expert at all, I just cannot understand a functional purpose for why they do it. Either way it was a let down for my intended use but I managed to get a decent result none the less

Great item would definitely recommend
Perfect just what I needed and great if you were adjustable rings and they go out of shape perfect for putting in them back in to shape just add a little pressure and turn it

Brilliant- sized up a ring
I was worried this would damage my ring that has a design on the outside but as the hammer head is soft, it did not. Took quite a lot of hitting, maybe half an hour or so of continuous hitting but it saved me like £50 compared to going to jewellers. I recommend this but only if you want to go up a size or a size and a half max, otherwise I don't think the metal would be able to take it and it may snap the ring.
