    I was actually expecting a kit, but this was pre-assembled and the item pictured seems to be an older version (mine is all surface mount). I appreciate the LED indicator and I’m using this with a 110v application – works great. Overall, price is very good for a solid product – quick shipping. THANKS!

    These are half the size of the relay boards sold at sparkfun, plus they are assembled. These are also of much better quality than the cheapos sold at ebay. Very reliable a well assembled. The one in the picture looks crappy compared to the one you will receive.
