Review on Cassida InstaCheck Counterfeit Detector With Infrared, Magnetic And Ultraviolet Sensors - Compact & Lightweight Automatic Detection System by Shawn Mortensen

I have 5 of these units between my two restaurants, one unit which I purchased about 45 days ago, the fail light does not work, because this SHOULD be under the warranty I contacted Cassida regarding a replacement. However, it has been over a week and now they are requiring me to mail back the defective unit first (frustrating but okay) but they also want me to mail it back in the original shipping box and retail box with manual, cord and everything. I do not keep boxes for every piece of equipment I purchase, this would be unreasonable. So I am hoping they make an exception but please BEWARE of their less than stellar customer service should you have an issue. Other than this unit, one other unit which is probably outside of warranty no longer beeps. So overall I am unhappy with their quality control and will be purchasing these from a different manufacturer in the future.
