valex13 I purchased the Radex Lupin. It works great for older laptops (like 5+ years old) as well as cars (even new cars). It also works great for detecting flicker in LED bulbs (I found that I was getting headaches, etc., from some LED bulbs that I had purchased). For me, LED bulbs below 5% flicker are just fine. Anything above, say, 30% flicker will cause noticeable problems. Anything in between is hard to say. I ended up walking around my house and replacing many of my LED bulbs with ones that flicker less.
KM I am very tempted to purchase the Lifli. It's totally worth the money to me if it works. I just don't want to waste $300+ on something that doesn't do what I want it to do. Would you say it does what's advertised? Specifically, will it detect PWM in newer laptops? I understand that it's not very precise because it only has 18 LEDs to indicate the amount of flicker.
