I purchased two of these early this summer. I found it to be easy to set up and very accurate. Within two weeks the digital readout started to malfunction leaving only a portion of the numbers legible. I paid for the return of it and another was sent to me that has worked well. The 2nd one, received as part of the original order, worked well for two months and then the same thing happened. Neither problem occurred after dropping it or other possible answers. I replaced the battery but the display continued to malfunction. When contacting the company, since it was under warranty, I was told I would need to send it back at my expense, pay another $8 for their costs and they highly recommended that I insure it as well. After realizing the cost I was incurring at this point was almost to the point of what I had paid originally – I decided to give up and try a different brand.
