Review on 🖨️ Enhanced PLA 3D Printer Filament: Next-Level Additive Manufacturing Solution by Mark Marcellus

I had high hopes for this thread. Unfortunately, this may be an exaggeration. I received my order today and am currently using it in my second print. The first started fine - until a break/flat on the filament hit the extruder and the extruder stopped extruding and skipped the break/flat. On a new roll. When I noticed a gap after about 10 minutes, I stopped printing, pulled the filament out of the hot end and extruder, cut it at the crease, reinserted it, and continued printing. About 90 minutes later it hit another kink/flat spot and this time I didn't notice it for 15 minutes before repeating the pause/refeed sequence. Unfortunately, 25 minutes with no filament coming out spoiled the print. I made sure the spool wasn't too tight and tried again. This time he walked for almost 2 hours, then there was another pause and he started sliding again. I looked closely and noticed it after only 2 minutes but I'm afraid it will keep happening even after I feed again. So the spool is practically useless if I have to pull/cut/refeed the filament every 100-120 minutes of printing, and any layers trying to print while it's not being extruded have a good chance of ruining the print . Looking at the spools it looks carelessly wound, I can see a few spots where the filament twists on itself and a few spots where the filament has been squashed against the side of the (clear) spool huh leads to kinks and flat spots. I have 20 spools of filament here and that's the only problem I've ever had. I'll let the current print finish (watch out for pull/cut/refeed) and then ask for a refund. Not sure I'll even need a replacement given how sloppy the spool is - I'm afraid I'll just end up with another bad reel. Very disappointed - I've heard good things about Sunlu and this is the first spool I've bought from them (I've also received another white PLA filament from Sunlu, I haven't opened the sealed box yet so I'll have a look watch carefully and if it looks like a careless wind, it will come back too).
