I own the PT18 Pro for about half year now, and I would rate it 10 stars without hesitation. I own a lot of flashlights(well known good brands), but the PT18 Pro is my absolute favourite tactical light. Performance is awesome, build quality is top-notch with premium materials and the part that I love the most is the User Interface. Simply the best U.I. I have ever seen on a flashlight. Tactical ring for perfect grip, instant Turbo, Instant Strobe, easy access to all power levels. Excellent, simple and reliable. I highly recommend it to everybody! The customer service is also excellent, every question that I had received an answer immediately. Congrats to all Brinyte team! You do an awesome job!
