    When it works it is nice. Charge battery, blue light comes on so i put battery in. When i put the battery cap on nothing happens. I have to keep messing with the cap, loosing and tightening until it will turn on. I thought battery was bad so i bought extra batteries and they do the same thing. Very disappointed with this product. Not even a year old.

      I have asked warranty to contact you – the contacts might need to be cleaned or something else may be going on, but warranty will be able to help you.
