SUNLU filaments are always great quality from my experience. I've used these on some printed spool holders I made a while back, and they fit great. Print quality has always seemed to be good on my Bambulab A1, and i haven't noticed any issues with adhesion, stringing, etc. that wasn't on my part. Definitely a good deal for the bundle of four.

I haven't had any issues with this product. I did have a issue with it not feed good when put on the reel, but that was my fault. Take your time when mounting in the reel.

I received this order on time, however, the refills do not fit in the reusable sunlu spools. They are too wide so the spools don't close and the cardboard center is much larger than the center hub of the sunlu reusable spools. I can't use these. Unfortunately it seems that I did not discover this until after the return policy allowed time.

Love, love, love the idea of refillable spools..... BUT.. .i've found, they are not neatly wound on the spool. this causes issues with the filament pulling and slipping into the gap along the wall of the spool causing many, many filament feed stops of print job. Not useable for long print jobs where I have to walk away. Yesterday I had to strip the last few meters off a spool and let it just feed into AMS. What was on the spool was wrapped really strange and was difficult to unspool... like it was stuck probably because it was not neatly wound was my guess. I love the product and the price... but I can't use it becasue of too many failures, it requirs constan monitoring to fix feed issues.

Seems to print good and is well packaged. They don't fit the existing SUNLU reusable spools tho? If I had read the description I would have maybe realized that. They are meant to fit the BAMBU spool which have a larger diameter mid sections. So when you place it on the SUNLU spools it just kind of flops around. Not an issue unless you don't already have a bambu spool of have an ability to print one.
