Faulty scope - Pulsar Digisight N750 Digital Night Vision Rifle Scope w/ IR Illuminator

This is my third Digisight scope. Has been very satisfied with my first two purchases so I purchased a third one. Worked well the first time. After two weeks in my gun safe, I took it out again to do some night plinking with my friends. Tried to turn on the scope and it just went dark. Put on new batteries and still won't work. Glad that I am still able to return it back at full refund. Hope this is just one of the defective scopes.
