For our purpose as a male engagement ring, to be worn for a couple of years until the wedding band replaces it, it suits us very well. The price was in a good bracket for a temporary, but nice ring. The edges are nicely curved to prevent grazing the skin. The diamond in the centre gives the groom a chance to decide whether they like having a centre for the ring and something to fiddle with, or whether they get annoyed with turning it round to face the whole time and want their wedding band to be universal the whole way round.
This ring is also available in a greater variety of sizes than wholesalers such as Argos.
After a few months of wear the matt finish is getting scratched and I imagine this will get worse as time goes on but I have not experienced this yet. If you don't mind this and your wedding band needs to be at a low cost then this is a very good choice for you.
