I won't repeat what I said before, but I must add this.

It have been a month and now I figured out: it's plated steel. I praticed twice a week and now the plate started to get off. Updated to 1 star. Honestly... I couldn't be more dissapointed.

I've heard Uday's rings are worth it for the price. I'll tell you something. These rings didn't come 100% silver color. Some rings have a somewhat "silver/goldish" aspect in some parts (the weld is fine, just the color is not ok). Also, the key show a sign of oxidation (I REALLY hope it's from the machine that made the key, not from the actual ring). It's marketed as "steel" alright... they should say if it's pure steel, cirurgic steel, stainless steel, chrome steel or plated steel. There's a huge difference. I cannot figure out exactly the kind of steel it is... all I can say with precision is this: For this price, go buy something else. This will get the job done but the quality is VERY LOW for the price. You can find WAY better rings in the same range of price. Think twice before buying from Uday (I sure will).
