I have had a Labradar for about five years and generally like it. The one SERIOUS ISSUE I have with it is that their software only works with Microsoft. My computer and cell phone are Apple and I can neither upgrade my software nor can I download ballistic data to my computer. I have discussed these problems with Labradar numerous times over the years but they do not seem interested in correcting them. Maybe some competition will motivate the company to address this.
