This is a good meter that I have been using for about 6 months, it has been great and has held its calibration. It is really nice that it has a internal rechargeable battery so I can unplug it and carry it to any system or area without having to plug it in! It also has a fold out stand on the back so when I am doing mixes I can prop it up right in my work area for easy viewing, also wall mountable. - Gary
