Title: does what it says and works well
Review: I bought three or four of these a while back not for my cigars but to simply keep an eye on humidity around my house (basement, garage, garage loft, etc.) and I'm pleased with how they work. I calibrated them all before placing them with salt and out of the box they were all within 3-4% and all are still functioning well. For the price it's hard to beat them.
