I gave it two stars because the heat mat did eventually turn up and it works. I ordered it on a Saturday and paid extra for the item to be delivered quicker (the website said by Tuesday)...but it had not even been dispatched until the day after it was due to arrive. And only then, I believe, because I emailed your company to check on it. Meanwhile, my gecko had no decent heating in his vivarium and I had to leave the house heating on in the living room all night during a spell of freezing weather. I did not get an apology just a matter of fact email saying it had at last been dispatched on the wednesday.... and it still did not arrive till Friday evening.... Not impressed.
