I've got the GTR Ultra-2's in both low and high beams, and am very pleased with their performance. The lows have a very even and sharp horizontal top line. I don't remember which high/low bulb, but it has the ability to clock the LEDs relative to the reflectors in the housing. Anything is better than the OEM halogens, but I find these a significant improvement over the original halogen and am not getting flashed by others. They were purchased through HR; their website generally sucks, but customer service after the purchase was good when I ordered the wrong turn signal bulbs (non-CK) and couldn't get them to work on my own. Not cheap, but still much less than switching to OEM LED housings.
With regard to hyped claims, I just got a letter from Diode Dynamics politely asking me on behalf of NHTSA to turn in my SL-1's I installed a few years ago in my 2017 Duramax Colorado. It seems some models of these LEDs output exceeds the DOT limits, so they'll gladly exchange them for some good, new halogen bulbs...
