"I purchased a 3018PROver and then subsequently purchased the laser bundle as well. The machine functions perfectly and is ideal for small CNC jobs. I had some trouble getting the laser to work, but George from Sainsmart tech. support was very helpful and gave me lots of advice, which helped a great deal."

"This is one company that stands behind their products. I had a problem with one of the TS80 irons and they quickly diagnosed issue and sent me replacement. I will definitely buy from them again with no hesitation."

"I had two issues with my Ender, and Ryan took the best care of my issues. I’m not very techie, but he explained how to send the information they needed to help me. I felt valued as their customer. This says a lot about this company."

"I purchased a 3018pro kit from Sainsmart. I chose Sainsmart over numerous other similar options because both in their product description and their website they had the most detailed information about the system. This gave me the confidence to order from them hoping that they would also have good customer support after the sale. They did not disappoint. I'm using the system in a non-standard way that pushes the performance in several respects. I received detailed answers to all my technical inquiries. For my project this was essential. I recommend them without reservation."

"The Printer was great, but it did have a bad power supply. I contacted support and they send out replacement unit."

"Very user friendly staff. Easy assembly. Looks like a very well thought out machine."

"The Genmitsu CNC router 3018-PRO arrived very quickly. The assembly was very easy due to the excellent video help.
I did have a problem with a bad fixing screw for the comntrol board and he switch was faulty. After informing the service deprtment I received a replacement and all is OK."

"Shipping was delayed because of COVID19 pandemic, but once clearing customs the package arrived in less than 24 hours.

The unit was easy to assemble and the instructions provided were very clear and use proper English grammar.

The machine works wonderfully, having a background in CAM I found it easy to work with. The files provided on the SD card worked "plug n' play", and the instructional videos provided were complete and easy to understand.

Customer service was very responsive and easy to deal with, will purchase from again!"

"I purchased an Ender 3 from Amazon, and everything was present. Unfortunately the top 2020 rail was drilled incorrectly, but I was ok with that as long as Sainsmart provided a properly drilled one. They did, and it was prompt in relation to the COVID 19 shipping environment! I appreciate that they fixed the issue, and luckily it was a redundant machine in my makeshift print farm of DIY/kit printers, so I was printing parts for it as I waited for the replacement part. Thank you Sainsmart!"

"Very good experience. Fast response from support and product came from Germany as they stated. There was no problem "upgrading" the shipping method after ordering. Product came within 4 days from ordering.
Booklet with building instructions is well written but maybe little too small. Product came with one defective screw that I had to replace. Have not tried any milling yet, just verified that the machine works with Mach 3 software.
I am satisfied with sainsmart so far."

"Updated on 22.05.2020: I have finally received the items (but I have already bought others from Amazon). SainSmart hat kindly offered me to keep them even after refund. I offered to pay at least half the price since the delay nowadays might not be completely their fault. The review stars were updated.

Updated on 06.05.2020: After 24 days from ordering without receiving the items, SainSmart offered to refund.
Even they claim that they have an EU-Warehouse, they will send all items belonging to one order from China only because one item is not available in EU-Warehouse. Therefore, I would recommend not combine several items in one order if not all items are available in the EU-Warehouse.
Four stars for the customer service.

25.04.2020: I still haven't received the items till now after 15 days from ordering !!!

"I've bought a few of their products and had no issue, until the CoreceptionXY. It would randomly turn itself off. After a couple of easy emails to their tech support, they quickly diagnosed the issue and gave me an easy workaround until a replacement part could be sent. I'll keep on buying their stuff, for sure."

"I've bought a CNC machine from Sainsmart; it came perfectly packaged, with great detailed instructions manual, and there is also video tutorials and even a wiki page with plenty of details. When/if even that isn't enough, their support team (I was assigned Polly) goes out of the ordinary to solve any problem you might have, and that alone earns them the 5 star rating."

"I bought the 3018 PR after thorough search for CNC kits. It's my seconds machine, so I felt confident buying a kit, but looked for recommended product and mainly supplier I can count on.
I had many questions before I issued purchase order, the answers were prompt and thorough.
I got my machine few days ago, already milling and enjoy it."

"Quick response , Quick replacement of faulty part. "
