Hand-Held Vein Detector Infrared Vein Finder - Handheld Chargeable Vascular Display Instrument Viewer for Elderly Children Easy Finding Subcutaneous Veins Device (Circular Vein Detector)

Not easy to use.

I have ordered this product for school purposes twice before only for the light to work about 6 months. Imagine my surprise when I received this package and the quality, sturdiness, etc. is fantastic. I would definitely order from this individual again.

poor quality visual display, does not appear as advertised
