Just got this today. It was very easy to set up, only took about 20 minutes or so. I used it tonight and it worked just fine. It took a while to get hot, but it did what it was supposed to do! I'm hoping it holds up and I can use it for at least a year or two. From the looks of others being sold, it is about the same thing as the units going for hundreds of dolors, so I thought I'd take a chance, and when it arrived, that suspicion was pretty much confirmed. The zippers look like they are in good condition. From review on other models zippers breaking seems to be the biggest issue, so even though I think these are going to be fine, I will be handling them pretty gently.
