First impression is good. I have two lights in my Chinese cupboard that I have converted from incandescent to GU10 bases. Brightness is perfect and color is good, albeit a little colder than warm white. After half an hour of operation, the lens cap rotated 140 degrees and the back of the lamp rotated 170 degrees. I've seen similar temperatures on other branded lights of a similar design and wasn't surprised. The last batch of GU10 PAR16 LEDs from another manufacturer started to burn out after 13,000 hours of operation at the same temperatures. Mine are set in small jars with a few holes in the top. Use in an open track lighting application can reduce temperatures. The plastic diffuser on this model is very good with a wide beam distribution and no hotspots. I hope for a lifespan of 12-15 thousand hours. I'll update the rating if things get bad, but for now I'm happy.
