Review on Manikins Compression Monitors Prestan PP IM 400M DS by Justin Early

The dummies came with all the features, the backlight worked well, but one of the dummies' arm kept falling off, even before my first training session. Unfortunately this was the one my assistant gave me for a demo and it continued even during practice which was quite embarrassing. Think it's a manufacturing defect. I'm already looking for ways to fix this to avoid further embarrassment.
