The SCART to HDMI adapter from Maplin is a quality item that allows you to connect SCART devices to HDMI and pass through HDMI. It comes with a power supply included, making it reliable in use.
This little box means I can use my video and DVD player which only had a scart output, and most new TVs only have HDMI now.
Very simple to connect... you need a scart and HDMI lead as the box has sockets, and the only lead supplied is the power one. (yes it needs a mains socket to work).
I had to press one button to set it to 1080 setting, a box appears on the screen to show the setting as the switches themselves are the press type and the instructions lost something in translation.
Don't know how reliable it is as only had it a few days, and not really used it other than to set it up.
