Be warned, Wismec has very poor manufacturing processes and very poor customer service. I have bought 4 RX2/3's and 2 RX200's. Out of the 6 mods, 5 have broke within a month due to poor manufacturing processes. All of the solder points are very poor and need a manufacturing process review to fix. The joints are very weak and will break with use in a very short period of time. I have contacted Wismec about this and they refuse to do anything. They keep coming up with different hoops that I have to jump through to get anything accomplished, and as of today nothing has been accomplished. It would seem, for the money you pay, that you would get a good quality product. I have pictures and an email chain to back my claims.
