I was looking for a small USPSA competition hat tube to help me check my individual results so I can try to learn from my speech. The picture and sound quality is fantastic and it's easy to play and watch videos with it. Two features that got me interested in this device compared to other products on the market: 1. The size is quite streamlined so it goes well with a baseball cap.2. It has an auto shut off feature after two (2) minutes. So if you forget to turn it off, no problem, it turns off after two minutes. It's only a month old and I've only used it in three games but I would recommend this product!
