Sunlu Reviews 

Great PLA, always quick delivery, happy with the product and highly recommended.

5* best filament out there. I've used many brands and different types and sunlu is by far the best. I've used pla+, pla, and high speed filament from sunlu and I have had no issues at all. Print quailty is amazing They are the only company I use now. Look forward to trying out the resin next.
Can review resin if you send a tester sunlu.

Amazing delivery times and price, SUNLU filament is my main choice, and it has never failed me. Great supplier and will most definitely use again and again.

Easy ordering, items (PETG) arrived via royal mail 48.
Always quick to respond to questions and technical support.

95% of my filaments come from Sunlu. Never had a problem with the spools, alway arrive in a timely manner...

I order all my filament from sunlu they are very reliable and fast delivery service. I know if I order just before I run out I will have my delivery in 2-3 days prompt. They have great and special promotions so it's best to register your email and buy accordingly as they're stock will go quickly. They have great choice of products of which I've had no issues with storage or use I always recommend to friends and associates.

I'm giving Sunlu 5 stars, as I find their filaments have been great values and good quality. The new PLA+ v2 has been excellent, once I tweaked the bed temp setting for better adhesion. The new reusable Bambu-compatible spools are a good bonus too.

Where Sunlu could greatly improve is answering email queries and actually having someone there answer their "Live" chat.
Postage is normally very swift.
But all in all, I'm happy to give 5 stars

I have been using sunlu pla since march this year and I now have 26 of their colours and have had no issues with the print quality. They have usually delivered within 5 days and on one occasion they were having difficulty in getting the colour I wanted so upgraded me to the higher quality spool at no extra charge 10 out of 10 for quality of product and service.

Excellent filaments

Not had any problems with either PLA, PLA+, PLA Matte or PETG

Very good prices
Free and reliable Shipping

And now they have even updated their spools to fit BambuLabs AMS units without the need for 3D printer adapters
Very happy

Since using Sunlu silk PLA I have experienced zero printing failures and the colour range is excellent
The delivery time scale is great

Have made loads purchases from sunlu and always received my parcels quickly, they sell top quality filament that always arrives in perfect condition.
The odd time when I have had a small problem customer services got back to me promptly to help me sort out my problem.

Customer service is non-existent. I placed an order, got an acknowledgement but that was it. No response to numerous emails and the chat bot on the website is pointless. Good filament, but don't buy directly. Fraudulent transaction dispute has been logged.

Ordered in their sale and a week later not fulfilled and ignoring my emails. Sale is a con.

Can't get hold of anyone and the wrong colour filament has been sent

Poor experience - I cancelled a pre-order with these guys and they ignored multiple emails and online requests and sent it anyway months later. The Phone numbers listed do not seem to work, they just ring out. They may have a uk presence, but are not UK based, emails seem to originate from China. Only after the item was shiped did they start responding to emails. The item shipped from a Ukraine postal service. I refused the delivery and it has been returned, but a month later i still havent been refunded.

I ordered 12 kg of filament on the Sunlu Website and got it delivered within a week. Once delivered and opened I noticed half of the filament was the wrong type.

I contacted customer service and I waited for 5 days with no reply. I then wrote another message, slightly aggravated at this point.
I waited another 2 days and got a reply, asking me to provide an unboxing video/pictures of the box and product labels. I replied within 5 minutes with pictures, no reply at all.

It's been 9 days today since I got someone to answer me from Sunlu and my patience is lost. Never again will I buy from this company.
The customer service is non existing and now I'm being forced to use filament I didn't order.

I ordered a dryer un January.and still not delivered. No replies.from customer.sercuce and no ewfunds given. This site is a scam

I would not buy a product from them again. My brother got 2 filament dryers on there Kickstarter and gave one to me as a present. It has failed with less than 30 heat cycles and I don't print large parts, so we are talking 30 mins to 3 hours per print. As I don't print that often it's out of warranty. Customer service got back to me in a reasonable time but were not very helpful after requesting photos and video, they said there was nothing they could do. No spare parts available to fix it which is very poor. Sadly my brother invested in a cheap quality under developed product with no parts back up. If you've read this I would not recommend you buy their products.

The filament prints well and now comes in reusable plastic spools.

Where this company falls off is their customer service, i keep telling them their cherry red is absolutely not what it should look like as it is an orange-pink rather than the standard cherry red color code you would think it would be. Way way brighter and not what i expected.... and they are going back and forth with me, throwing different reasons at me to reject my return, all in very vague emails from this "Amanda Lee" which i doubt is a real name anyways, judging by the lack of respect and low effort towards the emails and respecting their policy. You're much better off ordering through amazon at this point.

It took 17 emails before i gave up, this person kept insisting that i have opened the product and can't return it, but the only thing i opened was the postage bag. The filament bag was unopened. How would i even be able to see what i received if i didn't open the postage bag??

Thankfully i paid with paypal because i had to do this through PayPal to resolve it.

Absolutely unacceptable, you could almost call this a scam. If i had paid with my debit card there was most likely no chance of a return, and keep in mind that i had quoted their own return policy to this person 4 times and she still denies it!
