I tried the PETG my friends told me to try and it was good. Much better than PLA for most stuff. All of my PLA was from MakerGeeks, so I decided to try their PETG. It was so much better than the other stuff. Less stringy and easy to work with. It was beautiful from the first print. I can't seem to upload pictures here (i tried, not working...$(...). UploadHelper is not a function), but you can see a few of my Glow in the Dark PETG prints at http://www.thingiverse.com/make:*******, http://www.thingiverse.com/make:*******, http://www.thingiverse.com/make:*******, and http://www.thingiverse.com/make:*******. It doesn't actually look like glow in the dark plastic. More like natural plastic. The Smoke and HD Black is nice too, but I am loving the look of the glow in the dark even thought I can care less about the glow. I have 4 spools of Crystal PETG on the way. I'll review again after I have a chance to try them.
