We got a regular profile and an ultra thin ring, and both of them are superb. The rings themselves are exactly as stated on the website, and we are very pleased with them. If the thought of a simple no-nonsense ring made of titanium excites you in any way, I think this is a great option to consider.
The seller has been extremely helpful to us with all our enquiries, before and after sales. We initially ordered the wrong size of rings (we used HK chart numbers without converting into US sizes), but the store helped us through the process of getting the right ones with very little trouble. Thank you very much to Bruce and Chrissy for making it easy for us.
We used the cheaper USPS option for the shipping method (international shipping to Singapore), and it was surprisingly fast the first time, but the replacement rings took way longer than expected over the holidays. It seems the seller's manufacturing process lets them ship out the rings very quickly, but the shipping process is outside of the seller's control, and that's okay for us. If your needs are more urgent, you may want to pick a faster option for less variance.
Overall, we are very satisfied with the rings and the communication throughout. 10/10 would recommend to our friends.
