Relow Oven Controller is removed from Ebay.com soon after we sell it there. That was made becouse Ebay takes a commission for each maked order the prices are high and my advice is to use the order form from our official site. Another downside is that on Ebay you can't choose to buy only one unit and must order entrie unit with all the necessary modules for operation, but it is sometimes unnecessary if you already have one of them (ex . arduino).
