For the price, this filament can't be beat. Never have any real issues with prints. I've tried as many different colors and they all have came out great. No moisture issues, no tangling, works well at 220 nozzle and 55 bed for me. Adhesion is great. Colors have always been very consistent and vibrant. I originally bought it because it was the cheapest option and I didn't want to figure out how to print with an expensive filament and waste money on failed prints, but with how this has performed so far, I honestly don't see a reason to buy a more expensive brand, other than if SUNLU doesn't offer a specific type of filament.

It's an amazing choice for the average person in 3D-Printing. It's a great deal for what you get. As of my purchase, the price was $13-14 (not including tax/shipping). Compare this to the average of $15-20+ for other brands, especially printer manufacturers. Of course, it isn't perfect. The best way to describe it is kind of a "general" product in every category. It has decent quality, decently durability, decent flexibility, and overall is decent or pretty good in every category. You pay a basic price for a basic product, and that's not a bad thing at all. The thickness makes it ideal and compatible with most standardized printers from companies like Bambu Lab or Creality. It's very reliable and so far, and hasn't caused any problems, and I'm able to achieve any print speed I desire. It looks great when everything is finished as well, with consistent coloring throughout. I can't say for certain, but so far it appears to have decent moisture-resistance, being very forgiving if you can't store it in a dedicated or controlled environment. I don't have anything particularly negative to say about it, so I give it 5 stars for being a great product overall. I'm personally using a Bambu Lab printer with this filament, so I can say for sure that if you have a Bambu Lab printer then this filament is 100% compatible and an excellent choice if you don't want premium filament. I also like the fact that the spool holder is standard form, and also reusable.

Sunlu is one of the largest manufacturers of filament in the world. They make an absolutely excellent product. So much so , that many of the smaller names in the industry buy from Sunlu , either private label , or simply repackage them on their own. That should tell you right there that they are at the top of their game. The spools are neatly wound , the colors are vibrant , the printed results are phenomenal with no stringing or warping. The spools and filament perform perfectly 99% of the time. Id have to say any errors , if any at all are most likely user error. I only use Sunlu filament in all my prints because you just cant find a better option. They check off all the boxes.

This filament prints smoothly with little to no stringing. It has a good color and my earring two color prints look great with the white base and yellow centers. It’s definitely good filament at a good price

It is good filament for the cost. It is more brittle than many PLA's but it is also very transparent.

I’ve been using this SUNLU PLA for a while now and it’s been very dependable. The 1.75 mm filament feeds smoothly and I haven’t run into tangles or jams. Print quality is consistent, with good layer adhesion and a clean surface finish. I usually print around 200–210 °C and it works well with standard PLA settings. Bed adhesion has been good on both glass and textured plates, with minimal warping. The spool arrived vacuum-sealed and neatly wound, which I appreciate. For the price, this is a good quality PLA that’s easy to use and suitable for everyday prints, prototypes, and functional parts. I’d buy it again without hesitation

Love the color it’s exactly as expected. The temp range is fine, came sealed. The main reason I can’t give this a 5 is because the spool kept catching/causing issues with the print. It would jam and was would so tightly it snagged on itself! It appears to be a one off but it’s time consuming to keep checking the spool for large prints.
