A bit difficult to use at first this is a very sensitive meter that when coupled with an iPad or old cell phone can record like a meter costing five times as much. There is a learning curve but that's only a tiny hurdle to overcome and only for doing long recordings. As a handheld meter it is very easy to put into use and extremely sensitive like it should be. A good value and seems quite well made. I have a few other Testo products and they all have performed well.
