Hi Mike I had Elshan send me a green thresher replacement for the GMT hand which he did and also I asked him if he could send me another blue thresher because the loom on my first one was okay but not great. The second one blue one he sent me was a little bit better then the first one but nothing significant. The loom on the blue one is just not as strong as the green one. I am not sure how people were able to get it really glowing brightly on the blue one. I took many pictures and green was just brighter than the blue.
