PETG is relatively good…. I’ve seen other brands that print shinier and with less stringing but if you slow it down, there is no problem. Some of the spools were very tangled but some were ok but not perfect. The spools themselves are plastic which is nice if you have sn AMS. Will buy again because customer service is good and plastic is satisfactory. I really like the ABS. Wish list: more colors, more filaments (like ASA) and high speed (flow) filament.
