You are entitled to your opinion Eric, but your view on Chinese products is a little old fashioned. Like Konio-nt said, they are just alumium rings, nothing special in that, REAL Aluminium is used worldwide not just in your workshop, they're not made from platinium you know!
I have dealt with Chinese factories for nearly 9 years and in that time bought 100's of thousends of products, yes there is some crap out there but there are also some very good and highly equipped factories. The only difference between buying from you and the chinese is the chinese can make the same products for a fraction of the cost. You charge £25 for 3 aluminium rings, in China this price would be closer to £4.50 per set and thats being very generous in my estimation!
For example, I was quoted $10 (£5!!!) for rear brake discs for my Supra, I got a couple of FOC samples, fitted them to my car 15 months ago and they are still on there now, nothing wrong with the quality!
