I used it for the first time yesterday and it worked amazingly. I have been playing around with the settings and its very easy to dial in! The first thing I noticed about this sealer, vs others I have purchased is the build quality! Very heavy duty looking and well finished. Yes, I paid a little more, but after such bad experiences with several others, this really was my last one to try. Should have purchased this one first. We always want the cheapest, but in this case...don't do it! Best warranty I have seen, and great communication. I don't usually have time to write reviews, but this company deserves my taking time to do so.
