I ordered this additional receiver so that \I could use it with my original transmitter and receiver to use two separate remote flashguns.
It does exactly what it says on the tin and is very easy to set up and use.
When placing the order on line I incorrectly clicked for next day delivery to the store in Wardour Street instead of my home address. This was no problem as I was going to be in London later that week anyway. They already had the receiver as a stock item so very kindly refunded my P&P costs.
