I ordered this tungsten carbide ring for my soon to be husband as his wedding band. The sizes run big so I had to send it back twice to find the right size. TK returned the new sizes quickly which made for a smooth transaction. I am extremely happy with the quality, the look and of course the customer service. I will use TK for future purchases and suggest others use them as well. 
Bought this titanium kay ring On a Thursday and Paid for the 2 day shipping. Received it the next Tuesday and I was very pleased with shipping times. I made a trip to walmart and sized myself before I bought the ring. I ended up sizing myself at a 12 1/2 but since everyone said that they run big i ordered a 12. It is a little tight and I do have some trouble moving it past my knuckle but I know it won't fall off like my other ring. It fits very comfortably and is very LIGHT. It is however not scratch resistant and after less than 24 hours of having it, it's full of scratches, almost like the silver backing of an ipod touch. The good thing is that it doesn't show the scratches too bad. It's about 6/16 of an inch wide and looks great on my finger. Thanks Titanium Kay!
I bought these birthstone charms in sets of two based on the colors of me, my kids, and my husband. We are all birthstone charms blue or green. I like to use them to put on my SS hoops and give them just a small something extra. Its a great idea, and it is just that little touch of difference.
