Amazon these days is a new Ebay, only more expensive. Typically, on Ebay this board costs $5 each, or $10 for a pack of 4-6. Amazon item is different from Ebay boards not in quality (hard to believe in this), but in that it has plastic cover that goes around the back and rigid-mounted 1156 connector, while Ebay boards are self-adhesive with 1156 male connector on pigtail. I am not sure that plastic cover is better though. Contrary to what seller says, there is quite a bit of heat from boards of that size.
