Good price, but should mention it's only for black and not the colors shown in the pics. Probably worth it just for the reusable spools even though I've got a ton of black on hand, so in for one.

I'd be very cautious of this 3rd party seller. They're one of those that cancel all bad reviews by claiming it was a delivery issue when it clearly wasn't. Some reviews even mention them sending used, half-empty spools.

But Amazon, not the seller, fulfilled those orders with stuff coming off of shelves in Amazon's warehouses, so I'm not sure how that's the seller's fault. Clearly says that it ships from Amazon in the item description. Feel free to clarify your comment in case I'm missing something.

If it ships from Amazon, Amazon picked it off the shelf in their own warehouse and shipped it like that. If you receive something like that from Amazon, just initiate a return and send it back to them and get your refund. I once ordered a 4 pack of filament, sold by Sunlu and shipped by Amazon and received a single spool. I returned it, no questions asked.

Do you respool often? I've done it only a few times and it has been an adventure lol. I have a bunch of empty bambu spools but I just use adapters on my cardboard spools now. I wonder if there is a technique I'm missing. I do the masking tape thing so it shouldn't fall apart but it 's always such a tight fit that I have trouble closing both half of the spools together. At times some of my cardboard spools come bent out of whack which makes it hard to use an adapter and I'd like to throw them on a plastic spool but I've become a coward lol.

Good deal. I just bought a 4 pack of Sunlu High Speed PETG for $42 the other day so I'll skip on this this time. Works great on a P1S w/ AMS

I respooled a no name brand filament my daughter wanted onto a spool the other day using the PastaLite kit. It was not fun lol. The first half was a mess before getting the hang of it. I need to go back and redo it before using it.

No respooling here, but I believe they're compatible with Bambu refills. Considering the price Bambu gets for just an empty spool, these are nearly like getting free filament if you actually need the spools. (I don't and have way more black PETG than I need as it is, but you never know.)

I printed the Cell Spool Winder from Makerworld. Definitely bigger but it works amazing. As a bonus I can plug my handheld electric screwdriver into the axles hex hole, and use it to do all the work. Feels safer than using a drill lol.

For what it's worth I ordered this this morning and got it delivered this evening. Everything came sealed and in a box with a seal that said "do not separate."

https://www.amazon.com/SUNLU-High...ref=sr_1_4 I'd spend the $4.99 more for the high speed and get the official sunlu seller.

I've used this a couple of times and it's worked well enough. I like that it uses a drill too so it's quick without any real work.

I got a 4 pack (4KG/8.8lbs) of Creality PETG (for free on Temu, as part of the 20 Day Calendar promo (calendar1000). Not bad at all. You just gotta open up the calendar for 20 days. You don't have to buy anything daily, but occasionally a good deal will come up. Even got a $5 free credit promo on one of the days. For the 20th Day gift (the grand prize), I chose the Creality 4pk (8.8lbs) as the free gift with a min purchase of $35 (I got some screen printing supplies). Has anyone else tried this? I should be getting the filament in about 2 weeks
