Price, postage speed, and print quality
Good price, excellent postage speed, great range of filaments to choose from, all rolls were great, except one. One bag had a tangle before I even opened it I could see it through the plastic so I sent photos to customer support but they just said that happens sometimes sorry, try to untangle it or re spool it.. which of course I cant do... no offer to replace or refund etc which was a little disappointing. But all the rest have been great and print really well and i can use the roll with the slight tangle i just have to watch closely while printing with it.
