I bought this unit a few weeks ago and it works much better than the StrikeAlert Personal Lightning Detector. I've been using a smaller device for many years and this new model outperforms it in several ways. First, the new block is much more sensitive. I turned both devices on on a day of active weather and the StrikeAlert HD caught hits that the other device didn't. Also, the HD model doesn't seem to suffer from interference like the smaller model. All in all I would recommend this device.
