If there was a zero star rating I would…

If there was a zero star rating I would give it. I have been waiting for an item for months and they keep telling me it is out of stock and they are waiting for it to be restocked. I haven't asked for a refund yet just in case they eventually send it - it isn't available elsewhere and I currently have a FLSun S1 printer which is unusable. Do not buy this printer. It is very good until it needs a replacement part - which is quite soon - and then it is impossible to get the part.

Product Never Shipped, Refund Required a Chargeback

My experience with FLSun was deeply disappointing due to a complete failure in their fulfillment and customer service processes. An item I ordered and paid for in August never shipped.

When I cancelled the order, I was promised a refund within 3-7 business days (3 different times). These deadlines came and went. Most concerning was the communication: I was first told the refund was processed (twice), and then later told it was still waiting for approval in finance. This is unacceptable and misleading.

After being forced to file a chargeback with my bank, FLSun then began emailing me to cancel the dispute, claiming it was the only way to get my refund. This is a well-known tactic that puts the customer at risk.

Potential buyers should be aware of these significant issues. If you face a similar problem, I would advise you to rely on your bank's chargeback process, as it was the only way I could resolve my situation.

Extremely Slow & Unprofessional Process



I ordered the FLSUN S1 Pro half a month ago. After my purchase, they informed me they couldn't ship it from their EU warehouse. They spent days searching for shipping options from China, only to offer an unreasonably high shipping cost (€920). When I declined, they took even more time to lower the price—but by then, I had already purchased another printer elsewhere.

I requested a full refund (€1,836.88) immediately, yet they are still holding my money and say it will take another 3-5 business days to process.

This entire experience has been a complete waste of time—14 days of waiting, no printer, and still no refund. Absolutely unprofessional.

Very untrustworthy and shady company

Their printers can't hit the numbers they advertise. They change the terms of their promotion without notice and try to backdate announcements made after the fact. Their website only gives you the option to "accept all" for cookies and when you click the privacy policy button next to the accept all, it takes you to a page not found page.

Crooks!!!

Do not buy from them!!! First ever software issues then hard where issues and then we needed to send it back for repairs when they shipped it back it was damaged and it's been 6 months that you say the warranty is expired and they can't refund me even though it's not a warranty issue it's that they damaged or UPS damaged the product when it was being shipped back even though the product never ever worked.

Easy assembly with good instructions

Easy assembly with good instructions. My first delta printer and now my favorite- best first layer I’ve ever had and the best of my four 3d printers when it comes to dimensional accuracy. Reached out to customer service about a minor issue and got a quick and polite response. They had to check with another department and the next morning my answer was waiting for me. Very pleased with no complaints.

No Response was better than when they responded

Contacted support due to a firmware issue and got no response.

Contacted the third party I bought through and they have been good and managed to get through to Flsun however FLsuns advice has been abysmal.

They supplied incorrect firmware and completely corrupted the device. Now rather than replacing it they are asking me to completely rebuild the device from instructions from a dodgy git hub repository which has instructions as long as a book that also links out to other instructions equally long.

Warranty and Support does not exist

Bought a FLSun Q5 brand new which came with a 1 year warranty so felt reassured. Printer was working fine initially but started running into all sorts of self issues, i run multiple 3D Printers and i had never had such issues with them. Tried contacting their Skype support probably 50 or so times to try diagnose/repair the printer but nothing, the advertised warranty is not what you think it is and its basically non existent.

Better just getting an Ender printer.

Atrocious level of service

Pretty much horrible experience with their service. Ordered a printer off the flsun3d website, got a text saying delivery expected on Monday.

However tracking shows that Amazon (their fulfilment partner?) attempted delivery on Saturday and Sunday. So why was the text only delivered on Monday?

Delivery was attempted Monday and tracking noted parcel was rejected. A lie as we were in all day - not FLSUN's fault for this issue, fine.

More problems start when contacting FLSUN for help on Monday.

Service personnel do not bother to read past messages and require points to be reiterated multiple times on each following day. Service personnel should know better to read up on the client file.
Requests for follow up to be emailed were ignored, prompting me to have to navigate to my SMS, launch the page, and manually check for new messages every 24h - Chinese working time accounted for already. Why?
No follow up was initiated by the team. I had to manually chase for an update every one or two days. Service non-existent.
After 10 days since initiating a ticket, still no concrete updates. Only platitudes were given 'Don't worry friend, we will sort this out'. I don't care for platitudes - I want to know when my problem will be solved, how it will be solved, and what is being done to solve it.
No transparency on what is happening behind the scenes, or what the blocking issues are. Expectations not managed nor given.
Utterly ridiculous. Avoid like the plague. Not worth the hassle.
