Bests & Worsts Reviews from Amazon

I have just begun fermentation temperature control on my beer brewing and heard seed heat mats were the way to go to gently heat my fermentation chamber. I ordered this product expecting this would handle the heating side of things and was disappointed when it quit working within the week (Checked it with a multi-meter for a circuit and got nothing). Thinking I maybe I got a bad mat (stuff happens), I returned the product and repurchased the exact same model. The second mat arrived and lasted a little over a week before it died (verified with multi-meter). I unfortunately will not be going for a Round 3 with this manufacturer.
